The following set of numbers is going to be graphed on a histogram. 3, 19, 11, 29, 4, 6, 10, 16, 2, 21, 15, 22, 13, 9, 1, 17, 2, 26, 18, 7 if there are going to be six intervals in the display, what is the length of each interval?

We first calculate the range using the minimum and maximum data points of the set. the lowest value is 1, while the highest is 29. therefore, the range of the set is 29 - 1 = 28. if we have 6 intervals, then each interval should have a length of 28/6 = 4.667, but if these are only for integer data points, then each interval will have a length of 5 (the later intervals may have shorter lengths of 4).
