Question
Find the mean, median and mode of the following marks obtained by 16 students in a class test marked out of 10 marks:
0, 0, 2, 2, 3, 3, 3, 4, 5, 5, 5, 5, 6, 6, 7 and 8.
Solution
(i) Mean = `(0 + 0 + 2 + 2 + 3 + 3 + 3 + 4 + 5 + 5 + 5 + 5 + 6 + 6 + 7 + 8)/16`
= `64/16`
= 4
(ii) Median = Mean of 8th and 9th term
= `(4 + 5)/2`
= `9/2`
= 4.5
(iii) Mode = 5 as it occurs maximum number of times.
