10.2 Mean, Median, Mode. Page-208

   Exercise :- 2

Find the mean , median and mode of the following numbers

5 , 4 , 10 , 3 , 3 , 4 , 7 , 4 , 6 , 5

Solution :

a) Mean = (5 + 4 + 10 + 3 + 3 + 4 + 7 + 4 + 6 + 5)/10

             = 51/10

             = 5.1

b) Median : Arranging the numbers in order of size , we have

3 , 3 , 4 , 4 , 4 , 5 , 5 , 6 , 7 , 10.

The median is the “average” of 4 and 5

    Median = 4.5

c) Mode = 4 (there are more 4`s than other numbers)
