merits and demerits of mean, median mode slideshare

2. Used where mean and median can’t be used. 1.Effect of Extreme Value 2. Mean deviation is a measure that removes several shortcomings of other measures i.e. It can be easily calculated.2. Merits. May not figure in the series at all 3. Asssaalam o alaikum…These are measures of central tendency of the data.. You can also say that these are averages. Median = Merits of Median 1. it does not ignore extreme terms or values which play a significant role in average or Mean. Note that mode does not satisfy any of these, while (arithmetic) mean possesses all these four desirable characteristics. ; It is good for ordinal or interval sets of data. It is least affected by sampling fluctuations.6. Used for categorical data. Like median, mode can be found in some cases merely by inspection. The mode has an advantage over the median and the mean as it can be found for both numerical and categorical (non-numerical) data. i) Mode is readily comprehensible and easy to calculate. It is not capable of further mathematical treatment. M = size of (n+ 1)/2 th item, Demerits of median: Following are the various demerits of median: (1) Lack of representative character: - Median fails to be a representative measure in case of such series the different values of which are wide apart from each other. It is suggested for the average of ideal sizes, pocket money and also for open-end classed. 2. Also, median is of limited representative character as it is not based on all the items in the series. It is not affected by extreme values hence is a good representative of the series. The arithmetic mean can also inform or model concepts outside of statistics. Advantages of Arithmetic mean By making use of every values in the distribution, the mean is the most representative of all the averages __ Mean, Median and Mode The mean is the simplest of all averages –it is easy to calculate and simple to (d) … Merits and demerits of median : The following are some merits and demerits of median : (i) Merits : (a) It is easy to compute and understand. according to some Economists, mean Deviation is very useful for the forecasting of Business Cycles. Merits or Uses of Mode: 1. For example, in the sequence 3 6 3 11 4 3, the mode is 3. It can be used for qualitative data. Demerits of Median. It is the best measure to compare two or more series of data.7. Mode. MODE The mode … Based on all Items 4. Demerits. A slight change in the series may bring drastic change in median value. It is rigidly defined by the mathematical formula.5. Measures of Central Tendency - Mean, Median and Mode, Emperical Relationship of Mean, Median and Mode June 08, 2021 Meaning Central Tendency is stated as the statistical measure that the single value selected from the entire group of value or distribution or a dataset. Sometimes, just at … It is based on all values and can be subjected to further algebraic treatment. Sometimes the end figure is a decimal figure, which makes the data less meaningful. Merits and Demerits of Mean Deviation. The choice of an average is an important problem which a statistician has to face. ii) Mode is not at all affected by extreme values. 6.4.2 Merits and Demerits of Mode. Also, median is of limited representative character as it is not based on all the items in the series. The harmonic mean has the following merits. The mode has its limitations too. It can be found graphically also. It is also used in computing Fibonacci Sequences. median in case of 4, 7, 12, 18, 19 is 12 and if we add two values equal to 450 10000, new median is 18. Merits of Mean. The merits and demerits of harmonic mean are as follows: Merits: 1. This property makes it a better option than the mean as a measure of central tendency. Merits 4. Demerits. Mode is another unit of measurement of central tendency which is used to obtain a quick estimate of central tendency. Mode is defined as the particular value which appears again and again for maximum number of times in a set of observations. Merits or Uses of Median: 1. The column total is then taken and the one which has the maximum value is the modal value. Calculation of Corrected Mean. Median is the middle value among the observed set of values and is calculated by arranging the values in ascending order or in descending order and then choosing the middle value. The statistical methods play an important role in solving a problem & compiling the collected data, which can efficiently answer the questions relevant to the problem. Median is not influenced by extreme values because it is a positional average. Even if the value of extreme item is much different from other values, it is not much affected by these values e.g. Median in case of 4, 7, 12, 18, 19 is 12 and if we add two values equal to 450 10000, new median is 18. It is insensitive to some changes in the data values. According to Croxton and Cowden, ‘The mode of a distribution is the value at the point around which the items tend to be most heavily concentrated. Merits, Demerits and Uses of Mean Merits of Mean:1. We have discussed earlier the characteristics of a good average. Mode: The value of the variable which occurs most frequently in a distribution is called the mode. 3. Demerits are that it … Merits of Mode: 1. ; DISADVANTAGES. It requires intricate calculation. Demerits of Mean. Median can be located even if the data are incomplete. Mode. Merits of Median 3. It is rigidly defined. Arithmetic Mean And Range. Advantages: The mode is always a value that is actually in the set of numbers. 2. very small and very large items usually affect the value of average •Mean cannot be computed in case of open ended classes (b) It is well defined an ideal average should be (c) It can also be computed in case of frequency distribution with open ended classes. It is not affected by extreme values. 3. MERITS OF ARITHEMETIC MEAN l ARITHEMETIC MEAN RIGIDLY DEFINED BY ALGEBRIC FORMULA l It is easy to calculate and simple to understand l IT BASED ON ALL OBSERVATIONS AND IT CAN BE REGARDED AS REPRESENTATIVE OF THE GIVEN DATA l … The merits of mean are that it is easily calculated and easy to understands. MEAN The arithmetic mean (or simply "mean") of a sample is the sum of the sampled va lues divided by the number of items in the sample. 2. Accuracy Test. Mode can be also determined indirectly by applying the following formula: Merits of Mode Mode = 3 median - 2 mean In many cases it can be found by inspection. The dictionary meaning of the term mode is ‘most used’. The values are entered by means of a bar in the analysis table. (2) Not capable of algebraic treatment: - Unlike mean, mode is not capable of further algebraic treatment. Laughable Conclusions 4. Basis of Comparison 7. It is rigidly defined. Merits and Demerits of median & mode. Median: The median is that value of the series which divides the group into two equal parts, one part comprising all values greater than the median value and the other part comprising all the values smaller than the median value. (1) Simplicity:- It is very simple measure of the central tendency of the series. If there are extreme values (e.g. The measure for median is accurate over mean when the distribution of data is skewed. Mean: The mean is the most commonly and frequently used average. It can be located graphically. Unsuitability (%/proportionate values) 5.Misleading Conclusions. One makes use of all the available data so it is the most powerful measure to use. Certainty 3. The measures of central tendency are mean, median, and mode. It violates the algebraic principle by ignoring the + and – signs while calculating the deviations … The harmonic mean is useful in the finance sector to calculate the average multiples like the price-earnings ratio. Therefore it is mode class. Median can be calculated in case of distribution with open-end intervals. Mode. Mean, Median and Mode – A relative Evaluation. Generally median represents the mid-value of the given set of data when arranged in a particular order. Merits and Demerits of Median. It can be calculated for distributions with open end classes. Median. Meaning of Median 2. Not Affected by Extreme Values. Now the mode can be calculated with the help of the following formula. : Rate, Comment, Share... Thanx and Enjoy the videos. It is also the major measure of central tendency. 2. (ii) Unaffected by Extreme Values: Median is not affected by the extreme values. Simplicity 2. and thereby it can produce different results. Advantages and disadvantages of measures of central tendency. Merits of Mode: 1. The mean is the most common measure of central tendency used by researchers and people in all kinds of professions. (iii) Graphic Measurement: ADVERTISEMENTS: Median is rigidly defined as in the case of Mean. 3. 2. It is also the best representative of the series as it shows that value, which occurs most frequently in the series. Statistics, a vital element of society since ancient times is being used in almost every domain of activity. It is easy to understand.4. Merits of Mode: 1. it cannot be calculated ignoring any item of a series. Medians cannot be combined or weighed or in general, manipulated algebraically. It is the measure of central tendency that is also referred to as the average. The median is less affected by outliers and skewed data. The arithmetic mean of a series of values is the sum of the values divided by the number of values. • Find the mean, median and mode for the set of scores ihf di ibi blblin the frequency distribution table below Xf 52 4 3 32 2 2 11. Its calculation is based on all the observations.3. It represents group as well as extreme items and is not affected unless they are in modal class. ADVANTAGES. In statistics, the Arithmetic Mean (AP) or called average is the ratio of all observations to the total number of observations. 1. 3. 40. A researcher can use the mean to describe the data distribution of Meaning of Median: Median is the value of the middle item of a series when arranged in order of magnitude (ascending or descending order). Merits and demerits of mean Merits •It is simple average and easy to compute •It is makes use of all values of each item in the data Demerits •it is affected by extreme values i.e. MEAN. In a physical sense, the arithmetic mean can be thought of as a centre of gravity. • Female: 26 25 24 24 23 23 22 22 21 21 21 20 20 Thanks For Watching Subscribe to become a part of #TeamGyanPostSUBSCRIBE for awesome videos every day! It gives better result when the ends to be achieved are the same for the different means adopted. Even if the value of extreme item is much different from other values, it is not much affected by these values e.g. 2. It is based on all the observations of a series i.e. As far as merits and demerits of central tendency – median … Example 2 • The following data are representing verbal comprehi f l df lhension test scores of males and females. 3. Mean, Median, Mode etc. Another advantage of the median is that it does not get affected by an extreme value which is the case with mean. The most frequent number occurring in the data set is known as the mode. Merits and Demerits of Harmonic Mean. Stability 6. Only a glance is enough to figure out the modal value. Median is rigidly defined as in the case of Mean. It is not based upon all values of the given data. Merits. (3) Difficult: - With frequencies of all items are identical, it is difficult to identify the modal value. Thus it is the value, which occurs more often or with the greatest frequency. 2. - Maths Q&A What are the advantages and disadvantages of mean, median and mode? Mean is the most commonly used measures of central tendency. It actually represents the average of the given collection of data. It is applicable for both continuous and discrete data. 2. Demerits of Mode: 1. Merits of mode: Following are the various merits of mode: (1) Simple and popular: - Mode is very simple measure of central tendency. This is the only measure of central tendency that is useful for nominal data. 5. It is independent of the range of series. Demerits of Median 1. Demerits of Mode: Example 4: Calculate the value of mode for the following data: The modal value is 25 as it has the maximum total of 5 bars. It is based on all observation 3. It is not rigidly defined in the sense that it is computed from any central value viz. The measure for median is accurate over mean when the distribution of data is skewed. Medians cannot be combined or weighed or in general, manipulated algebraically. As far as merits and demerits of central tendency – median are concerned, there are several of which to take note. It is easily understandable and computable. 2. 4. Mode is the term that occur most in the series hence it is not an isolated value like Median nor it is value like mean that may not be there in the series. For larger data size the arrangement of data in the increasing order is difficult process. Following are the various demerits of mode: (1) Uncertain and vague: - Mode is an uncertain and vague measure of the central tendency. Demerits of Median 1. 6.4.2 Merits and Demerits of Mode. Mode = l + cf2/f1+f2 Where l is the lower limit of the model class, c is its class interval f1 is the frequency preceding the highest frequency and f2 is the frequency succeeding the highest frequency. In case you would want to calculate the mean, then this sequence has a mean of 5 which is not actually a part of the sequence. Relative merits and demerits of Mean, Median and Mode. Demerits of median: Following are the various demerits of median: (1) Lack of representative character: - Median fails to be a representative measure in case of such series the different values of which are wide apart from each other. This necessitates a relative evaluation of these three measures of central tendency. Following are the main merits of the median: (i) Simplicity; ADVERTISEMENTS: It is very easy to calculate and is readily understood. It can be easily observed from the data. In a busy road, where we take a survey on the vehicle - traffic on the road at a place at a particular period of time, we observe the number of two wheelers is more than cars, buses and other vehicles. It is capable of further algebraic treatment. Hence for example, if in the above data if one replaces $10000 with $100000 the also median will come to $6000 whereas mean would have increased from $6000 to $24000 due to one extreme value.
