To answer the question, refer to the following list of raw data.
63, 71, 72, 77, 77, 78, 86, 77, 88, 88
What is the median for the data?
A. 77.7
B. 88
C. 77.5
D. 77

Solution

The median of the data is defined as first arrange the data in increase values.

63 71 72 77 77 77 78 86 88 88

Let n is the sample size, if the sample size is odd then we get the median is by (n+1)/2

if the sample size is even then we get the median is the average of n/2 and (n+2)/2

Here

The average of n/2=77 and (n+2)/2=77 is 77

So, the median is 77.
