Question

The last digit of the heights of 66 statistics students were obtained as part of an experiment conducted for a class. Use the frequency distribution to construct a histogram.

Digit Frequency
0 16
1 3
2 5
3 4
4 5
5 14
6 5
7 5
8 4
9 5

What can be concluded from the distribution of the​ digits?

Answer 1

The histogram is shown below.

You'll have 10 bars. Under each bar is a label from 0 to 9. The height of each bar represents the frequency of each units digit.

The histogram shows two bars that are relatively large compared to the rest. These bars have frequency of 16 and 14 (for units digits of 0 and 5 respectively). The distribution is nearly bimodal. If the two frequencies mentioned were the same, say both 16, then it would be exactly bimodal. As you can probably guess, bimodal means "two modes".

The rest of the bar heights are nearly the same, so the remaining portion of the distribution is nearly uniform. A uniform distribution has every bar the same height. Collectively, all the bars of a uniform distribution forms a larger rectangle.
