Prepare a frequency distribution table for the above data using class intervals of equal width in which one class interval is 4−8 ( excluding 8 and including 4).

In this table class intervals are such that Lower limit is included and upper limit is not included in the class.

That means In interval (4−8), 4 is included but 8 is excluded.

And for frequency we counted how many times number from the interval occurs in given data.

Class interval Frequency

4−8 2

8−12 7

12−16 13

16−20 6

20−24 2

Total 30
