Central Tendencyyp and the Shape of the Distribution • We have identified three different measures of central tendency, and often a researcher calculates all three for a single set of data. Measures of Dispersion 29 MEASURES OF DISPERSION You have learnt various measures of central tendency. which measure of central tendency you would use if you are (1) the employer, and (2) a trade union representing the employees. A measure of central tendency is a summary statistic that represents the center point or typical value of a dataset. Measures of central tendency are examples of descriptive data statistics that depict an overall ‘central’ trend of a set of data. answer choices . B)the difference between the 20 th and 80 th percentiles. Mean. The range is a very simplistic measure and does not use all the scores in the data set therefore it can be distorted by a very high or low score that does not reflect the range of most of the other scores in between those two points. Reports of central tendency are commonly supplemented and complemented by including a measure of dispersion. Measures of central tendency tell us what is common or typical about our variable. Which measure of central tendency would best depict the following data: 10, 200, 200, 300, 325, 350 and 400? It is an estimate of a “typical” value. 300 seconds . Another way to communicate with your friend would be to use measures of central tendency like the mean, median and mode.

Central tendency is defined as “the statistical measure that identifies a single value as representative of an entire distribution.”[] It aims to provide an accurate description of the entire data.It is the single value that is most typical/representative of the collected data. They tell us the central value around which the data is distributed. The dispersion of a data set is the amount of variability seen in that data set. Range. False. Since what counts as a “center” is ambiguous, there are several measures of central tendencies. You subtract the lowest score in the data set from the highest score to give the range. Measures of central tendency are very useful in Statistics. This section will look at two types of summary statistics: measures of central tendency and measures of dispersion. While measures of central tendency are used to estimate "normal" values of a dataset, measures of dispersion are important for describing the spread of the data, or its variation around a central value. Mean. When dispersion is low, the central tendency is more accurate or more representative of the data as majority of the data points are near the typical value, thus resulting in low dispersion and vice versa. The mode will be the most frequent score in the given set of data. Measures of central tendency are the most basic and, often, the most informative description of a population's characteristics.

Defining the middle of a distribution as where the scores are divided into two equal-sized groups is the basis for the _________ . Measure of central tendency is a single value to describe a set of data by identifying the central position within that set of data. There are three key measures: Mode – the most frequently occurring number in a data set. A histogramis a type of graph in which the x-axis lists categories or values for a data set, and the y-axis shows a count of the number of cases falling into each category. As the name suggests, the measure of dispersion shows the scatterings of the data. Measures of dispersion are used to describe the variability or spread in a sample or population. Measures of central tendency are mean, mode and median. A measure of central tendency (also referred to as measures of center or central location) is a summary measure that attempts to describe a whole set of data with a single value that represents the middle or center of its distribution. Can the central tendency describe the data fully and adequately? The mode is the least used of the measures of central tendency and can only be used when dealing with nominal data.
