The distribution, given below, shows the marks obtained by 25 students in an  aptitude test. find the mean, median and mode of the distribution.

 Marks obtained 5 6 7 8 9 10 No.of students 3 9 6 4 2 1

#### Solution

 Marks obtained(x) No.of student (f) c.f fx 5 3 3 15 6 9 12 54 7 6 18 42 8 4 22 32 9 2 24 18 10 1 25 10 total 25 171

Number of terms=25

Mean=171/25=6.84

Median= (25+1^("th"))/2 "term" = 13^"th" "term" =7

Mode = 6 as it has maximum frequencies i.e. 6
