It’s the easiest measure of variability to calculate. To find the range, simply subtract the lowest value from the highest value in the data set. Range example You have 8 data points from Sample A. Data (minutes) 72 110
Start by writing the computational formula for the variance of a sample: s2 = ∑x2 − (∑x)2 n n−1 s 2 = ∑ x 2 − ( ∑ x) 2 n n − 1 2. Create a table of 2 columns and 6 rows. There will be a header row and a row for each data value. The header
