Question

8.Find the mean median and mode of the following ungrouped data
(i)3,5,3,7,2,5 and 3
(ii)82,85,78,79,89,87,88,89,75,77,90,88,89,82,and 88

Answer 1

Answer:

First arrange data in ascending or decending order

(I) mean = 28/7 = 4

median = (n+1)/2=(7+1)/2= 4th term = 3

mode= 3

(ii) mean= 1179/15=78.6

median = (15+1)/2 = 8th term = 87

mode = 88,89
