Step-by-step explanation:
Below are an example using the data values
{ 11 , 10 , 17 , 18 }
Step 1: What is MAD?
MAD is the average distance between each data value. <MAD> is used to see variation of the data. The larger the MAD, the further apart the numbers are.(and vice versa)
Step 2: Find the mean
11 + 10 + 17 + 18 = 56
56/4 = 14
Step 3: Formula to find the Absolute Deviations or distance of the data value to the mean
Find the absolute value of the difference between each data value and the mean: | data value – mean | or I mean - data value I
Step 4: Find the Absolute Deviations
14 - 11 = 3
14 - 10 = 4
17 - 14 = 3
18 - 14 = 4
Step 5: FInd the mean of the Absolute Deviations or MAD
3 + 4 + 3 + 4= 14
14/4 = 3.5
