If the p-value is less than a specified significance level (α) (usually 0.10, 0.05, or 0.01), you can declare the difference to be statistically significant and reject the test's null hypothesis. One way to calculate significance is to use a z-score. To this end, we need to consider statistical significance. The lower the p-value (< 0.01 or 0.05 typically), stronger is the significance of the relationship. This number reflects the probability of obtaining results as extreme as what you obtained in your sample if the null hypothesis was true. Response Rates. Statistical and practical significance. If there is a large sample size, then small difference in the research findings can be negligible if you are very sure that the differences did not arise out of fluke. The simplest way to determine whether a statistical hypothesis is true would be to look at the whole population. A p -value less than 0.05 (typically ≤ 0.05) is statistically significant. Last week, I learned how to distinguish the statistical significance and economic significance while doing the regression analysis in my econometrics class. a p-value of 0.05 is equivalent to significance level of 95% (1 - 0.05 * 100).

The number of conversions for both control and variation(s). The second building block of statistical significance is the normal distribution, also called the Gaussian or bell curve.The normal distribution is used to represent how data from a process is distributed and is defined by the mean, given the Greek letter μ (mu), and the standard deviation, given the letter σ (sigma). Once you conduct your analysis, you will get a p value, also called a significance (Sig.) Statistical significance means that there is strong statistical evidence that a true difference exists within the full population. It is found that there is about 28% chance of getting such results with a diet that has no effect. In most sciences, including economics, statistical significance is relevant if a claim can be made at a level of 95% (or sometimes 99%). Understanding Statistical Significance Additional Step for Two-tailed Test. For a simple comparison, the z-score is calculated using the formula: z = x − μ σ The level of significance is denoted by the Greek symbol α(alpha). I performed a paired T-test using the actually numbers, but am now questioning myself as to whether I should be using the standardized incident rate instead. the probability of finding a given deviation from the null hypothesis -or a larger one- in a sample. This post isn’t about teaching Stats 101. Statistical significance is the mean to get sure that the statistic is reliable. Limiting interpretation of research results to p values means that r … The difference between a sample statistic and a hypothesized value is statistically significant if a hypothesis test indicates it is too unlikely to have occurred by chance. (2013). Therefore, the level of significance is defined as follows: Statistical significance depends on 2 variables: The number of visitors, i.e your sample size. 101 1 1 bronze badge.

Statistical significance between … Determine your hypothesis. It’s possible for hypothesis tests to produce results that are statistically significant, despite having a small effect size. Statistical significance dates to the 1700s, in the work of John Arbuthnot and Pierre-Simon Laplace, who computed the p -value for the human sex ratio at birth, assuming a null hypothesis of equal probability of male and female births; see p -value § History for details. Share. A p-value of 5% or lower is often considered to be statistically significant. How to Determine Statistical Significance When A/B Testing With Divi Leads. To calculate the F-test of overall significance, your statistical software just needs to include the proper terms in the two models that it compares. It's based on Comparative Error and difference between percentages for the given statistical data. That’s a +28.7% increase in conversion rate for variation B. While there are a limited set of situations when this is okay, it is never ideal. See the formula to calculate the test statistic, an example, and how to interpret the result. Although this is by no means a comprehensive guide, it includes some of the most common tests and situations … Calculating statistical significance and the p-value with 20.000 users. In medical terms, clinical significance (also known as practical significance) is assigned to a result where a course of treatment has had genuine and quantifiable effects. References: Moore, D. S., Notz, W. I, & Flinger, M. A. Another way of thinking about this is that the smaller the probability that the result was random, the more confident you can be that your changes are what caused the result. How to determine statistical significance in shell. Next, calculate the sample mean. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. This formula helps us determine that there is a relationship in the differences or variations. Population: The reach or total number of people to whom you want to apply the data. Clinical Significance Statistical Significance; Definition. Statistical hypothesis testing is the method by which the analyst makes this determination. 90%. How to calculate statistical significance 1. For example, there may be potential for measurement errors (even your own body temperature can fluctuate by almost 1°F over the course of the day). When you’re determining the statistical validity of your data, there are four criteria to consider. Statistical evidence, therefore, contributes to our level of confidence in research findings, rather than relying on human judgement or bias. Since that is often impractical, researchers typically examine a random sample from the population. When we perform a t-test, we use the t-distribution to model the null hypothesis. Let’s take another A/B test example: version A: 10,000 users – 108 conversions – 1.08% conversion rate. a test planned for α = 0.05 that passed with a p-value of just 0.0499 will have exactly 50% observed power (observed β = 0.5).

how to determine statistical significance

by an analyst that the results in the data are not explainable by chance alone. Follow asked 5 mins ago. “Statistical significance helps quantify whether a result is likely due to chance or to some factor of interest,” says Redman. Things like conversion rate statistical significance, bounce rate statistical significance, transaction rate statistical significance, and so on; really anything that either did or did not happen in some proportion. The terms to look for in a study are whether the results were clinically significant, clinically important, or met the required MCID. determine the significance level beta Hypothesis Testing: procedure Eight steps procedure: rejection region method Step 1: state H0 and H1 H0: the null hypothesis no difference between sample and population H1: the alternative hypothesis opposite of H0 Step 2: find the distribution of the test statistic statistic: observed sample … It merely tells us that this value is (5.231) significantly different to zero. The confidence interval (also called margin of error) is the plus-or-minus figure usually reported in newspaper or television opinion poll results. The first step in calculating statistical significance is to determine your null hypothesis. One-Sided Z-Score: 2.33. ... hypothesis-testing statistical-significance t-test chi-squared-test. The idea behind statistical significance testing is that anytime you gather a sample of data (e.g., hiring rates for a janitorial position, average salary for accountants) and compare two groups (e.g., men and women), due to chance alone, it is extremely unlikely that the difference between the two groups is going to be exactly zero. In fact, there is a 1 to 1 inverse relationship between observed power and statistical significance, so one gains nothing from calculating post-hoc power, e.g. The most common way to test statistical significance is Pearson’s chi-squared distribution, so called because it was invented by a man named Pearson, “Chi” is “x” in Greek, and the test asks users to square their data to accentuate the differences. Probability or percentage: The percentage … To assess statistical significance, examine the test's p-value. The everyday meaning for "significant" is quite different from the statistical meaning of significant. This lesson explains two-tailed tests, one kind of statistical significance test. Your statistical software package will return this number to you once you conduct your analysis. Statistical significance is a statement about the likelihood of findings being due to chance. Next, create an alternative hypothesis. Statistical Significance Is there a relationship (difference) or isn’t there a relationship (difference)? The first thing you need to do when trying to determine statistical significance for such a test is establish exactly what level of confidence you would be comfortable with for your results. Pretty … Determine a proper sample size to be used for analysis. If the comparative error (c) < difference (d) then there is significance. These 3 factors are: 1. Determine the significance level. Statistical significance is the probability that your split test’s result was due to random chance. A 5 Step Model for Null Hypothesis Significance Testing 1. A t-test requires that the independent variable be bivariate, i.e., having only two … The level of statistical significance is often expressed as a p -value between 0 and 1. Next, calculate the population mean. If sample data are not consistent with the statistical hypothesis, the hypothesis is rejected. Sample … I'm curious how to determine whether two datasets are statistically similar from a two-sample t-test (ttest2). How to calculate statistical significance. Next, calculate the population mean. The basic practice of statistics (6th ed. Data users should not rely on overlapping confidence inter-vals as a test for statistical significance because this method will not always provide an accurate … First, determine the sample size. Formula to calculate statistical significance. I understand that the result gives the decision to reject (1) or accept (0) the null hypothesis, but how does the null hypothesis decision give statistical significance? Statistical hypothesis testing Also remember, the p-value is not an indicator of the strength of the relationship, just the statistical significance. Statistical significance is a term used by researchers to state that it is unlikely their observations could have occurred under the null hypothesis of a statistical test.Significance is usually denoted by a p-value, or probability value.. Statistical significance is arbitrary – it depends on the threshold, or alpha value, chosen by the researcher. Hello I’m Michael Aagaard – thank you for watching this short video on how to determine the statistical significance of an A/B split test. Statistical significance is a term used by researchers to state that it is unlikely their observations could have occurred under the null hypothesis of a statistical test.Significance is usually denoted by a p-value, or probability value.. Statistical significance is arbitrary – it depends on the threshold, or alpha value, … A t-test is designed to test for the differences in mean … In this example, we took some steps with the help of Python to determine the statical significance of having a profile picture to the result of the total sales of an item. Even when we find patterns in data, often there is still uncertainty in various aspects of the data. State the null and alternative hypotheses. Hot Network Questions Copy a file content to clipboard with dired How to make a 1x city bike easier to ride uphill? of sampling (is not statistically significant). Statistical Significance Example. V0b Relative Risk Cutoffs for Statistical Significance 2014 Milo Schield, Augsburg College 2014‐Schield‐RR‐Statistical‐Significance‐0b.doc Page 5 Figure 5: Maximum RRss for any combination of P1 and N as a function of P1*N Various rules give different minimums to justify using this normal approximation. Statistical Significance. Two-Sided Z-Score: 1.64. Determine a proper sample size to be used for analysis. When you conduct a survey or other research, the analysis is based on the sample of a population, not the entire population as a whole. Testing the significance of Pearson's r. We have looked at Pearson's r as a useful descriptor of the degree of linear association between two variables, and learned that it has two key properties of magnitude and direction. Calculate the mean of the sample. Statistically, significant study findings are frequently recognized as clinically … Significance testing refers to the use of statistical techniques that are used to determine whether the sample drawn from a population is actually from the population or if by the chance factor. To assess statistical significance, examine the test's p-value. Significance. Test the significance by checking whether the difference calculated above (d) is greater than the comparative error this way: If the comparative error (c) > difference (d) then there is no significance. The number of conversions for both control and variation(s). The second building block of statistical significance is the normal distribution, also called the Gaussian or bell curve.The normal distribution is used to represent how data from a process is distributed and is defined by the mean, given the Greek letter μ (mu), and the standard deviation, given the letter σ (sigma). Once you conduct your analysis, you will get a p value, also called a significance (Sig.) Statistical significance means that there is strong statistical evidence that a true difference exists within the full population. It is found that there is about 28% chance of getting such results with a diet that has no effect. In most sciences, including economics, statistical significance is relevant if a claim can be made at a level of 95% (or sometimes 99%). Understanding Statistical Significance Additional Step for Two-tailed Test. For a simple comparison, the z-score is calculated using the formula: z = x − μ σ The level of significance is denoted by the Greek symbol α(alpha). I performed a paired T-test using the actually numbers, but am now questioning myself as to whether I should be using the standardized incident rate instead. the probability of finding a given deviation from the null hypothesis -or a larger one- in a sample. This post isn’t about teaching Stats 101. Statistical significance is the mean to get sure that the statistic is reliable. Limiting interpretation of research results to p values means that r … The difference between a sample statistic and a hypothesized value is statistically significant if a hypothesis test indicates it is too unlikely to have occurred by chance. (2013). Therefore, the level of significance is defined as follows: Statistical significance depends on 2 variables: The number of visitors, i.e your sample size. 101 1 1 bronze badge.

There are many online calculators available to help you determine whether the difference in your test results was significant. Typically, your alternative hypothesis is... 3. In statistical tests, statistical significance is determined by citing an alpha level, or the probability of rejecting the null hypothesis when the null hypothesis is true. Conversion range. Calculate the mean of the entire population. A t-test is a method of assessing statistical significance by comparing the means of dependent-variable distributions observed during an experiment. ... Statistical significance between … Determine your hypothesis. It’s possible for hypothesis tests to produce results that are statistically significant, despite having a small effect size. Statistical significance dates to the 1700s, in the work of John Arbuthnot and Pierre-Simon Laplace, who computed the p -value for the human sex ratio at birth, assuming a null hypothesis of equal probability of male and female births; see p -value § History for details. Share. A p-value of 5% or lower is often considered to be statistically significant. How to Determine Statistical Significance When A/B Testing With Divi Leads. To calculate the F-test of overall significance, your statistical software just needs to include the proper terms in the two models that it compares. It's based on Comparative Error and difference between percentages for the given statistical data. That’s a +28.7% increase in conversion rate for variation B. While there are a limited set of situations when this is okay, it is never ideal. See the formula to calculate the test statistic, an example, and how to interpret the result. Although this is by no means a comprehensive guide, it includes some of the most common tests and situations … Calculating statistical significance and the p-value with 20.000 users. In medical terms, clinical significance (also known as practical significance) is assigned to a result where a course of treatment has had genuine and quantifiable effects. References: Moore, D. S., Notz, W. I, & Flinger, M. A. Another way of thinking about this is that the smaller the probability that the result was random, the more confident you can be that your changes are what caused the result. How to determine statistical significance in shell. Next, calculate the sample mean. The smaller the p-value, the stronger the evidence that you should reject the null hypothesis. This formula helps us determine that there is a relationship in the differences or variations. Population: The reach or total number of people to whom you want to apply the data. Clinical Significance Statistical Significance; Definition. Statistical hypothesis testing is the method by which the analyst makes this determination. 90%. How to calculate statistical significance 1. For example, there may be potential for measurement errors (even your own body temperature can fluctuate by almost 1°F over the course of the day). When you’re determining the statistical validity of your data, there are four criteria to consider. Statistical evidence, therefore, contributes to our level of confidence in research findings, rather than relying on human judgement or bias. Since that is often impractical, researchers typically examine a random sample from the population. When we perform a t-test, we use the t-distribution to model the null hypothesis. Let’s take another A/B test example: version A: 10,000 users – 108 conversions – 1.08% conversion rate. a test planned for α = 0.05 that passed with a p-value of just 0.0499 will have exactly 50% observed power (observed β = 0.5). Statistical … The first step in statistical significance testing is to adopt a null... 2. Definition and meaning. Statistical significance, or a statistically significant result, are terms commonly used by statisticians which few of us properly understand. When a statistic is significant, it means that the person is fairly sure that it is reliable. Many times it is dependent on the method or tool used to … Interpret your results. When a press release or article claims results to be statistically significant, it usually means researchers used a certain procedure to calculate a p-value, and that number was smaller than 0.05. “One common misconception is that binomial results should be based solely on P-value to determine significance.” Click & Tweet! The final step of statistical analysis is interpreting your results. Determine whether the results below appear to have statistical significance, and also determine whether the results have practical significance. Let’s work through a sample size example Let’s say you want to find out how many people in your region of 10,000 inhabitants favor a longer school day for children. P-values are the gatekeepers of statistical significance. In the digital community, it’s not uncommon to see A/B testing tools make calls at only 80% or 85% confidence. This … Conduct and interpret a significance test for the mean of a Normal population. Sample Size Calculator Terms: Confidence Interval & Confidence Level. Describe the parts of a significance test.

Statistical significance is calculated using a p-value, which tells you the probability of your result being observed, given that a certain statement (the null hypothesis) is true. If this p-value is less than the significance level set (usually 0.05), the experimenter can assume that... Today I’m going to go over 3 basic factors that are essential to establishing the reliability of your test results. Statistical tests can be used to analyze differences in the scores of two or more groups. It’s called a sample because it only represents part of the group of people (or target population) whose opinions or behavior you care about. In general this information is of very little use. When a finding is significant, it simply means The size of your population will depend on your resources, budget and survey method. Usually, statistical significance is determined by the set alpha level, which is conventionally set at .05. Next, calculate the sample mean. 2. Statistical significance is a scientific method that helps to determine whether reported research findings are actually true. For a Z-test, the normal distribution curve is used as an approximation for the distribution of the test statistic. A t-test is used to determine if the scores of two groups differ on a single variable. Enter statistical significance. One is the significance of the Constant ("a", or the Y-intercept) in the regression equation. 3. Active today. To set up calculating statistical significance, first designate … Using a Sample Size Calculator to Ensure Statistical Significance. The formula for the t-test is as follows. Statistical significance is a great way to examine data and determine if a variable has an impact on the final outcome. If the p-value is less than a specified significance level (α) (usually 0.10, 0.05, or 0.01), you can declare the difference to be statistically significant and reject the test's null hypothesis. One way to calculate significance is to use a z-score. To this end, we need to consider statistical significance. The lower the p-value (< 0.01 or 0.05 typically), stronger is the significance of the relationship. This number reflects the probability of obtaining results as extreme as what you obtained in your sample if the null hypothesis was true. Response Rates. Statistical and practical significance. If there is a large sample size, then small difference in the research findings can be negligible if you are very sure that the differences did not arise out of fluke. The simplest way to determine whether a statistical hypothesis is true would be to look at the whole population. A p -value less than 0.05 (typically ≤ 0.05) is statistically significant. Last week, I learned how to distinguish the statistical significance and economic significance while doing the regression analysis in my econometrics class. a p-value of 0.05 is equivalent to significance level of 95% (1 - 0.05 * 100). How to calculate statistical significane. Statistical Significance - Overview, Example, Use in Business 0. Part 1 of 3: Setting up Your Experiment Define your hypotheses. The first step in assessing statistical significance is defining the question you want to answer and stating your hypothesis. Set the significance level to determine how unusual your data must be before it can be considered significant. Decide to use a one-tailed or two-tailed test. ... Determine sample size with a power analysis. ... Step 3: Determine Statistical Significance of Results. To carry out a Z-test, find a Z-score for your test or study and convert it to a P-value. Create a null hypothesis. There are two main ways that small effect sizes can produce small (and thus statistically significant) p-values: 1. Use the following as a guideline to think about test significance: If the difference between the tests was very small, it may be that the … -Statistical Significance: We will look at the t-tests or p-values to determine whether or not to reject the null hypothesis … If, say, the p-values you obtained in your computation are 0.5, 0.4, or 0.06, you should accept the null … Report the result of the one-way ANOVA (e.g., "There were no statistically significant differences between group means as determined by one-way ANOVA (F(2,27) = 1.397, p = .15)").Not achieving a statistically significant result does not mean you … In order to determine the level of statistical significance of our results, we’ll have to calculate four expected values, given the number of variations we’re dealing with: the number of people who clicked on version A, the number of people who clicked on version B, and Significance Level. Determine significance from a table. Statistical significance is the likelihood that the difference in conversion rates between a given variation and the baseline is not due to random chance. The “P” value, frequently used to measure statistical significance, is the probability that the study results are due to chance rather than to a real treatment effect. This describes the distance from a data point to the mean, in terms of the number of standard deviations (for more about mean and standard deviation, see our page on Simple Statistical Analysis). Once you have learned the correlation coefficient ( r ) for your sample, you need to determine what the likelihood is that the r value you found occurred by chance. Calculate the statistical significance of your results in seconds using our calculator! For any experiment, there is a null hypothesis, which states there’s no relationship between the two things you’re comparing, and an alternative hypothesis. Which statistical test to use to determine if two disjoint subsets are significantly different? Classical significance testing, with its reliance on p values, can only provide a dichotomous result - statistically significant, or not. This is not my first take … : Broadly speaking, statistical significance is assigned to a result when an event is found to be … Calculate the mean of the sample. Decide on the type of test you’ll use. The conventional cut off for the “P” value to be considered statistically significant is of 0.05 (or 5%). Statistical Significance Example. Understanding Statistical Significance and. We’ve personally found 95% to be a sweet … How to calculate statistical significance The first step is to form a hypothesis. Below is a simple diagram to help you quickly determine which test is right for you. The term "statistical significance" or "significance level" is often used in conjunction to the p-value, either to say that a result is "statistically significant", which has a specific meaning in statistical inference (see interpretation below), or to refer to the percentage representation the level of significance: (1 - p value), e.g. value. Confidence Level. Create a null hypothesis and an alternative hypothesis. In a study of a weight loss program, 5 subjects lost an average of 50 lbs. Statistical Significance Explained. How much traffic do I need for my A/B test? Definition: Statistical significance is used to find whether the given data is reliable or not and it does not have any decision-making utility. The concept of statistical significance is central to planning, executing and evaluating A/B (and multivariate) tests, but at the same time it is the most misunderstood and misused statistical tool in internet marketing, conversion optimization, landing page optimization, and user testing. To do so, it's critical to understand the connection between clinical and statistical significance. Which p-value thresholds for a two-sided 90% confidence interval? Part A. State hypotheses. One-way ANOVA (cont...) My p-value is greater than 0.05, what do I do now?. There are so may statistical tests out there it can be difficult to determine which is the right test to use. A statistically significant result isn’t attributed to chance and depends on two key variables which are sample size and effect size. Calculate the mean of the entire population. Comparing the computed p-value with the pre-chosen probabilities of 5% and 1% will help you decide whether the relationship between the two variables is significant or not. 2. A result of an experiment is said to have statistical significance, or be statistically significant, if it is likely not caused by chance for a given statistical significance level. First, determine the sample size. to the claim that a result from data generated by testing or experimentation is not likely to occur randomly or by chance but is instead likely to be attributable to a specific cause. Ask Question Asked today. If the test is one-tailed, leave the number calculated in step 3 … Statistical significance helps you determine if the results of your analysis are likely to have happened by chance, or if they truly are an accurate reflection of reality. The following statistical tests are commonly used to analyze differences between groups: T-Test. One standard statistical analysis is the p-value. When can I stop my split test? The significance level (also called alpha) is the threshold that you … Statistical significance is a determination by an analyst that the results in the data are not explainable by chance alone. He or she then collects data and performs statistical analyses to determine if the data did in fact support the hypothesis. Sample size is the number of completed responses your survey receives. Statistical vs. Economic Significance. As a result, the p-value has to be very low in order for us to trust the calculated metric. Before I start collecting data, I find it helpful to state my hypothesis at … The overall F-test compares the model that you specify to the model with no independent variables. For this example, alpha, or significance level, is set to 0.05 (5%). Clinical and Statistical Significance Understanding and interpreting research is essential for effective evidence-based practice implementation. Each of the stats produces a test statistic (e.g., t, F, r, R 2, X 2) that is used with degrees of freedom (based on the number of subjects and/or number of groups) that are used to determine the level of statistical significance (value of p). How to calculate statistical significane. Set a Null Hypothesis. Set a threshold for statistical significance. Set the significance level to determine how unusual your data must be before it can be considered significant. One-Sided Z-Score: 1.28. One of the most important issues when conducting survey research is to determine the number of returned survey responses necessary to produce valid and reliable results. version B: 10,000 users – 139 conversions – 1.39% conversion rate. ). For example, if you use a confidence interval of 4 and 47% percent of your sample picks an answer you can … Create an alternative hypothesis. If your P-value is lower than the Cite.

Büntetőjog

Amennyiben Önt letartóztatják, előállítják, akkor egy meggondolatlan mondat vagy ésszerűtlen döntés később az eljárás folyamán óriási hátrányt okozhat Önnek.

Tapasztalatom szerint már a kihallgatás első percei is óriási pszichikai nyomást jelentenek a terhelt számára, pedig a „tiszta fejre” és meggondolt viselkedésre ilyenkor óriási szükség van. Ez az a helyzet, ahol Ön nem hibázhat, nem kockáztathat, nagyon fontos, hogy már elsőre jól döntsön!

Védőként én nem csupán segítek Önnek az eljárás folyamán az eljárási cselekmények elvégzésében (beadvány szerkesztés, jelenlét a kihallgatásokon stb.) hanem egy kézben tartva mérem fel lehetőségeit, kidolgozom védelmének precíz stratégiáit, majd ennek alapján határozom meg azt az eszközrendszert, amellyel végig képviselhetem Önt és eredményül elérhetem, hogy semmiképp ne érje indokolatlan hátrány a büntetőeljárás következményeként.

Védőügyvédjeként én nem csupán bástyaként védem érdekeit a hatóságokkal szemben és dolgozom védelmének stratégiáján, hanem nagy hangsúlyt fektetek az Ön folyamatos tájékoztatására, egyben enyhítve esetleges kilátástalannak tűnő helyzetét is.

Állandó, komplex képviselet

Még mindig él a cégvezetőkben az a tévképzet, hogy ügyvédet választani egy vállalkozás vagy társaság számára elegendő akkor, ha bíróságra kell menni.

Semmivel sem árthat annyit cége nehezen elért sikereinek, mint, ha megfelelő jogi képviselet nélkül hagyná vállalatát!

Irodámban egyedi megállapodás alapján lehetőség van állandó megbízás megkötésére, melynek keretében folyamatosan együtt tudunk működni, bármilyen felmerülő kérdés probléma esetén kereshet személyesen vagy telefonon is.  Ennek nem csupán az az előnye, hogy Ön állandó ügyfelemként előnyt élvez majd időpont-egyeztetéskor, hanem ennél sokkal fontosabb, hogy az Ön cégét megismerve személyesen kezeskedem arról, hogy tevékenysége folyamatosan a törvényesség talaján maradjon. Megismerve az Ön cégének munkafolyamatait és folyamatosan együttműködve vezetőséggel a jogi tudást igénylő helyzeteket nem csupán utólag tudjuk kezelni, akkor, amikor már „ég a ház”, hanem előre felkészülve gondoskodhatunk arról, hogy Önt ne érhesse meglepetés.
