Because there are 50 numbers, we can divide these numbers into groups of 10 (5 groups).... Next we subtract the lowest number from the highest number (76 — 16 = 60).... After this, we will divide the difference by the number of groups that we came up with (60 / 5 = 12).... hellip; Once we get the class width (12), we add it to the lowest number in order to get the lowest class limit (16 + 12 = 28)....
