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.

How this one works

One question from this sheet, worked through a step at a time.

Range of 11, 38, 45, 11, 20

1138451120
1138451120
4511=34
  1. The range is not an average at all — it is how far it is from the smallest to the biggest.
  2. The smallest is 11 and the biggest is 45, so take one from the other: 45 − 11 = 34.
