Question The heights in inches of commonly grown herbs are shown. Organize the data into a frequency distribution with six classes, and think of a way in which these results would be useful.
Answer I think there are many ways to organize the data into a frequency distribution with six classes. You may sort data, count the frequency of each value, and then reasonably group values into classes. For example, we may group data into the six classes: 7-12, 14-15, 16, 18, 20, 24-36 or 7-10, 12-15, 16, 18, 20, 24-36; and then interpret the data in terms of number of commonly grown herbs in each class as well as cumulative frequency.
Hope it is helpful. Please feel free to ask me any questions about it.
