Answer

Then, average these absolute deviations: 10+5+0+5+105=6

Steps

Step 1 ：First, calculate the mean (average) of the data set: 5+10+15+20+255=15

Step 2 ：Next, find the absolute deviations of each data point from the mean: |5−15|=10,|10−15|=5,|15−15|=0,|20−15|=5,|25−15|=10

Step 3 ：Then, average these absolute deviations: 10+5+0+5+105=6
