Data: 70, 50, 90, 120, 110, 100, 80, 60
The median of the data set is
Median refers to the value which lies in the middle of the data (when arranged in an increasing or decreasing order).
Arranging the data in ascending order: 50, 60, 70, 80, 90, 100, 110, 120
Since no. of observations is 8, an even number, there will be two middle terms. So, the median will be the average of (82)th and the (82+1)th terms.
Median will be the average of the 4th and 5th terms
So, median = 80+902 = 85.
