Step-by-step explanation:

Given : 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

To find : What is the median of this set of data.

Solution : We have given the data set 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

Arranging in increasing  order :  29, 51, 54, 60 , 64 ,66, 66, 67, 68, 75, 77,80.

There are 12 numbers of set
