What ranges of scores have a frequency of 1

20-30 & 40-50

Step-by-step explanation:

To find which range of scores have a frequency of 1, let's break it all down into separate ranges.

20-30: 1

30-40: 2

40-50: 1

50-60: 2

60-70: 6

70-80: 9

80-90: 13

90-100: 5

We can see in our different ranges that the range 20-30 and 40-50 have a frequency of 1.

How did we find this?

Analyze the chart and find which area shows the range, the bars are the frequencies of the different ranges.
