The range is the difference between the smallest and highest value in the sample.
Example: we have collected the age of 15 men and 14 women as follows
- Men: 18, 19, 23, 25, 30, 30, 35, 36, 39, 45, 54, 66, 66, 66, 74 -> Range(men) = 74 – 18 = 56 yrs
- Women: 19, 19, 24, 29, 37, 39, 48, 57, 69, 70, 72, 75, 82, 83 -> Range(women) = 83 – 19 = 64 yrs
