Explanation:
Detailed explanation-1: -Measures of Variability The range is the simplest measure of variability. You take the smallest number and subtract it from the largest number to calculate the range. This shows the spread of our data.
Detailed explanation-2: -If all data values are the same, then, of course, there is zero variability. The graph of the distribution would have zero width. If all the values lie very close to each other there is little variability and the distribution’s graph would be quite narrow.
