Question

This data set represents the number of

children in 8 families

4, 2, 1, 2, 4, 2, 6, 3

The mean of this data set is 3. What is the

Mean Absolute Deviation (MAD)?

A. 1.25

B. 8

C. 3.3

D. 3

Answer 1

Answer:

1.25

Step-by-step explanation:

Lets sum up the values

24

and then divide by their number (8)

we get 3 on average

now let's see how much each data point varies from that average (this is always a positive value)

1, 1, 2, 1, 1, 1, 3, 0

Let's sum and divide by 8 again

10/8 = 1.25

(would really, reallly appreciate the brainliest)
