In statistics, dispersion is the extent to which a distribution is stretched or
squeezed. Common examples of measures of statistical dispersion are the
variance, ...

YOU must decide which measure of dispersion best describes the spread in a set
of data. The range is the crudest way to estimate the spread of the data values.

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 ...

We're going to be dealing with, as you see, the population measures of
dispersion. I know these are all fancy words. In the future, you're not going to
have all of ...

A variance measures the degree of spread (dispersion) in a variable's values.
Theoretically, a population variance is the average squared difference between a

INTRODUCTION. 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.
