Definition
Measures of Variability (Grouped) are statistical tools used to describe how data values are spread out or dispersed around the central tendency in a grouped frequency distribution. They show the degree of variation or consistency among data values within the class intervals. Common measures include the range, mean deviation, variance, and standard deviation.
Summary
In grouped data, variability helps us understand how widely the data values differ from the mean or from each other. Since exact data points are not available, class midpoints and frequencies are used to estimate these measures.
These measures are essential for understanding how consistent or variable data are within a group. A small variability indicates that data values are close to the mean, while a large variability means they are widely spread out.
