The measure of the scattering of items in a distribution about the average is called dispersion. Calculate
range, variance and standard deviation of the data
Answers
Answer:
Suppose you are given a data series. Someone asks you to tell some interesting facts about this data series. How can you do so? You can say you can find the mean, the median or the mode of this data series and tell about its distribution. But is it the only thing you can do? Are the central tendencies the only way by which we can get to know about the concentration of the observation? In this section, we will learn about another measure to know more about the data. Here, we are going to know about the measure of dispersion. Let’s start.

Measures of Dispersion
As the name suggests, the measure of dispersion shows the scatterings of the data. It tells the variation of the data from one another and gives a clear idea about the distribution of the data. The measure of dispersion shows the homogeneity or the heterogeneity of the distribution of the observations.
