Question

Sum of mode and median of the data 12,15,11,13,18,11,13,12,13 

a. 26 

b. 31 

c. 36 

d. 25

Answer 1

Given data, 12, 15, 11, 13, 18, 11, 13, 12, 13

First put the numbers in ascending order, 11, 11, 12, 12, 13, 13, 13, 15, 18

The mode of a data set is the number that occurs most frequently.

Here, 13 occurs three times.

So, Mode = 13.

Median is the middle number in the data set after arranging in ascending order.

Here, middle number in the data set = 13.

So, Median = 13

Sum of mode and median = 13 + 13 = 26.

Hence, the sum of mode and median is 26.
