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

26

Step-by-step explanation:

Let us re arrange the data in ascending order to find the median.

11, 11 , 12 , 12 , 13 , 13 , 13 , 15 , 18

The mode is the number with the highest frequency , from the data , 13 appears three times , which is more than the appearance of the other numbers , therefore , 13 is the mode.

Median is the middle number , therefore , the median is 13

So, the sum of the mode and median = 13 + 13

= 26
