Enter all values in the chart below before moving on to #7 Excel directions for the histogram Class width=(max-min)/4= (always go up to the next whole number) Class Frequency Midpoint Excel Statistics Graphs Lab Page 3

Answer 1

Solution:-

By observing data from given table, we obtained

Maximum value = 13 and

Minimum value = 3

So,

Class Width = (max - mini)/2 = (13 -3)/4 = 10/4 = 2.5≈3

So, Class Width = 3

Using this class width and given table , the chart is completed as shown below-

Class	Frequency	Mid Point
3-5	5	4
6-8	4	7
9-11	6	10
12-14	5	13
