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

Answer: 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
