Question

The stem-and-leaf plot shows the scores of Jon's basketball team for the year.

What is the range of the basketball scores?


53
52
30
38

Answer 1

I would say that the range was 120.

Answer 2

how?

Answer 3

Add all the numbers then subtract by the highest number.

Answer 4

Underneath the plot it shows how to read the plot: "3|8 represents 38". Looking at the top row of the plot, there are two scores of 38. Can you see what the three scores in the bottom row are?

Answer 5

The bottom row is 6 | 1 3 8.
6 is the first (most significant) digit of each of the three numbers. So we have 61, 63 and 68. So the lowest number in the top row is 38 and the highest number in the bottom row is 68.
The range is therefore 68 - 38 = ?
