For his statistics project, Martin recorded the weights of some apples.

Question

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.
