Draw up a frequency distribution table classified on the basis of marks with class-intervals of 5.

Class-intervals Tally marks Frequency

Of marks

25-29 / / / / // 7

30-34 / / / / (^) / / / / 10
35-39 / / / / (^) / / / / /// 13
40-44 / / / / /// 8
45-49 / / / / (^) / / / / /// 13
50-54 / / / / / 6
55-59 /// 3
60-64 /// 3
65-69 / 1
70-74 / 1
Total 65
Now the required frequency distribution is shown below :
Frequency distribution of marks obtained by 65 students
Marks Frequency
25-29 7
30-34 10
35-39 13
40-44 8
45-49 13
50-54 6
55-59 3
60-64 3
65-69 1
