Question

A customer service center keeps track of the number of complaints received each day about one of their new products. The numbers of complaints received over the last 11 day period are​ 19, 18,​ 22, 21,​ 17, 18,​ 22, 19,​ 16, 23, and 25. What is the median for this​ sample?

Answer 1

19

Explanation:

To find a median of sample the first thing we need to determine is whether the sample size is even or odd. Since we have 11 day period this means sample size is odd.

For odd sample size, we arrange the sample in ascending or descending order and the middle term of the series is median.

In our case the arranged sample in ascending order is as follows:

16,17,18,18, 19,19, 21,22,22,23,25

The middle term is the 6th term which is 19

Answer = 19
