The histogram has 4 bars with the same height, which means that there are 4 groups of data points. Each group has 5 data points (as the width of each bar is 5), so the total number of data points is 4 times 5, which is 20. However, each data point could have a value between 0 and 3, so there are actually 4 times as many possible values, which is 20 times 4, or 80. However, only 22 of these values are actually present in the given data set.
