Answer:
Hey stu132057, your the MAD for the data set given is
Step-by-step explanation:
Step 1: Find the mean of the data: (14+13+16+12+17+21+26)/7 = 17
Step 2: Find the difference between each data and mean:Difference between 14 and 17 is 3
Difference between 13 and 17 is 4
Difference between 16 and 17 is 1
Difference between 12 and 17 is 5
Difference between 17 and 17 is 0
Difference between 21 and 17 is 4
Difference between 26 and 17 is 9
Step 3: Add all the differences: 3+4+1+5+0+4+9 = 26
Step 4: Divide it by the number of data:26/7 = 3.7
So, the MAD = 3.7
