Question

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 Students (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 sumf = 25 sum fx = 171

Mean barX = (sum fx)/(sumf) = 171/25 = 6.84

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

Since the number 6 has maximum frequency 9

∴ Mode  = 6

Is there an error in this question or solution?
