The largest value minus the smallest value, measuring the spread of a data set.
Revise: Processing and presenting dataAn average describes a typical value; the range describes spread. Two groups can have similar averages but very different spreads.
The difference between the largest and smallest values in a data set.
Check the selected cell range: including a total or omitting a value changes the calculation.
Subtracting the last and first cells gives the range only if they contain the maximum and minimum. Recheck this after changing data.
Compare matching measures: mean with mean, median with median, and range with range.
