Question

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

Answer 1

Mode=13 (most frequent)

Median= (n+1)/2 th term = 9+1/2 th term = 5th term = 18

Sum of mode and median = 13 + 18 = 31

Answer 2

The sum of mode and median is 26.

Step-by-step explanation:

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.
