Question

Find the mean absolute deviation for the set below:

62, 71, 83, 110, 501, 94, 227

Answer 1

Step-by-step explanation:

First, add all the numbers and count the total amount of numbers.

Once you've done that find the mean by dividing the total of the numbers by how many numbers you have.

Next make a chart, have 2 parts in the chart. Make boxes for however many numbers you have. Make another row in the chart for the distance from the mean ( how many numbers is it from the mean.)

Add all the "distance from mean" numbers and divide by total numbers, If a decimal, round up or down.

Then, you have the M.A,D ( Mean Absolute Deviation )

Answer 2

(MAD) mean absolute deviation: 114.2

Explanation:

Mean: 62 + 71 + 83 + 110 + 501 + 94 + 227 = 1,148/7 = 164

164 - 62 = 102

164 - 71 = 93

164 - 83 = 81

164 - 110 = 54

164 - 501 = 337

164 - 94 = 70

164 - 227 = 63

Mean Absolute Deviation: 102 + 93 + 81 + 54 + 337 + 70 + 63 = 800/7 = 114.2
