Solution.     Frequency distribution: It tells how frequencies are distributed overvalues in a frequency distribution. However mostly we use frequency distribution to summarize categorical variables.

Marks Number of students CF f
0- 20 17 17
20- 40 22 22-17 = 5
40- 60 29 29 -22 = 7
60- 80 37 37-29 = 8
80-100 50 50 -37 = 13
