Question

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

Step-by-step explanation:

1.mode=3

median=3

mean=n+1 by 2 =3+1 by 2 = 2

Answer 2

Answer:

(I) Mean = sum of all terms / total number of terms => 3+5+3+7+2+5+3=28/7=> 4

Median = Arrange them in increasing order than find the term in the middle of the sequence.

Increasing order => 2,3,3,3,5,5,7 so, the median is 3.

Mode : The number which is repeated the most. And that is 3.
