Range of a data set worksheets
The range measures how spread out a set is: the largest value minus the smallest. These free printable worksheets practice that single subtraction — the simplest measure of spread — with an answer key.

What's on this sheet
Range is a fact about spread, not about the center, and pairing it with the mean is what makes both mean something: two sets can share a mean of 50 while one runs from 48 to 52 and the other from 5 to 95. The range is what tells those two apart, and it needs no ordering — only spotting the biggest and smallest numbers in the row.
Why this sheet works
Because it depends on the two extremes and nothing in between, a single unusual value stretches the range on its own. That is worth noticing rather than hiding: it is exactly why the interquartile range exists, and why a child meets the plain range first. Every answer here is a whole number, the difference of two whole numbers.

45−11=34
- The range is how far it is from the smallest to the biggest.
- The smallest is 11 and the biggest is 45, so 45 − 11 = 34.
