How to Find the Mean Absoulte Deviation

Data Set: 6, 5, 7, 4, 3

Step 1: Find the mean of the list of numbers.

6+5+7+4+3= 25/5= 5

Step 2: Find out the distance/difference of one numbers in the data set and the mean. Do this for all numbers in the data set.

1, 0, 2, 1, 2

Step 3: Find the mean of those numbers.

1+0+2+1+2= 6/5= 1.2

Mean Absolute Deviation: 1.2

Innerqaurtile Range

Data Set: 5, 9, 2, 4, 8

Step 1: Find the median.

2, 4, 5, 8, 9 = 5

Step 2: Not including the median, find the median of the numbers on the left of the median and the right of the median.

2,4= 3 8,9= 8.5
