Range (Measure of Dispersion)

In Class 9 Mathematics, Range is introduced in the Statistics chapter as a simple measure of dispersion. Students learn to find the range of a data set by subtracting the smallest observation from the largest observation. The topic helps them understand how widely data values are spread and compare the variability of different sets. Examples and practice with ordered and unordered data strengthen accuracy in identifying maximum and minimum values and interpreting results.
