The measures of central tendency are not adequate to describe data. Two data sets can have the same mean but they can be entirely different. Thus to describe data, one needs to know the extent of variability. This is given by the measures of dispersion. Range, interquartile range, and standard. Dispersion: Variance, Standard Deviation A variance measures the degree of spread (dispersion) in a variable’s values. Theoretically, a population variance is the average squared difference between a variable’s values and the mean for that variable..
a measure of dispersion closer in size to the mean deviation. Let us calculate s 2 and s for our three groups—Tom’s, Dick’s, and Harriet’s—whose mean deviations were 0, 0.5, and 2.0, respectively. MEASURES OF DISPERSION 77 Q 1 is the size of n th +1 4 value. n being 11, Q 1 is the size of 3rd value. As the values ar e alr eady arranged in ascending or der, it can be seen that
Measures of dispersion provide information about how much variation there is in the data, including the range, inter-quartile range and the standard deviation. Range The range is simply the difference between the maximum and minimum values in a data set. Range The simplest measure of dispersion is the range The range is the difference between the minimum and maximum values in a group of observations

Similar to measures of central tendency, a particular value that describes the variability of a collection of data describes the measure of dispersion. The variability in data is measured using the values of the set of data along with the help of central tendency measures.. CHAPTER В­ 6 MEASURES OF DISPERSION Points to rememeber * Dispersion is a measure of the variation of the items from central value. * The measures of dispersion are important to compare uniformity, consistency and reliability amongst variables/ series.

Unit 4: Statistics Measures of Central Measures of Dispersion •Tell you how widely spread out the values are •Most common are Range, Standard Deviation, and Variance Range •The range of a data set is the difference between the maximum and minimum values in the set •Example: >In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. Example: In {4, 6, 9, 3, 7} the lowest value.

After studying this chapter, you should be able to. provide the importance of the concept of variability (dispersion). measure the spread or dispersion, understand it, and identify its …. Measures of Dispersion Zigya App Open ended distributions are those distribution in which either the lower limit of the lowest class or the upper limit of the highest class or both are not specified.. In statistics, dispersion has two measure types. The first is the absolute measure, which measures the dispersion in the same statistical unit. The second type is the relative measure of dispersion, which measures the ratio unit. In statistics, there are many techniques that are applied to measure dispersion..
