Question

For his statistics project, Martin recorded the weights of some apples.
Apples' weights (g)
70
80
90
100
110
120
What was the range of the apples' weights?

Answer 1

To find the range of a set of data, you subtract the smallest value from the largest value.

In this case, the weights of the apples are:

- 70 g
- 80 g
- 90 g
- 100 g
- 110 g
- 120 g

The smallest weight is 70 g, and the largest weight is 120 g.

Now, calculate the range:

\[
\text{Range} = \text{Largest value} - \text{Smallest value}
\]
\[
\text{Range} = 120 \, \text{g} - 70 \, \text{g} = 50 \, \text{g}
\]

So, the range of the apples' weights is **50 g**.
