Find the mean absolute deviation (MAD) of the data in the pictograph below.

The MAD is 1.5

Step-by-step explanation:

To find the MAD we have to find the mean, let's put the graph from least to greatest...

2, 3, 4, 7

We have to add all the number then divide it by how numbers there are, in this case there are 4...

2 + 3 + 4 + 7 = 16 ÷ 4 = 4

The mean is 4...

Now, we have to find the distance of each number on the graph is from 4

4 - 2 = 2

4 - 3 = 1

4 - 4 = 0

7 - 4 = 3

(Pretend it can't be negative)

Now, we have to add the distances from 4 and calculate the mean with these new numbers...

2 + 1 + 0 + 3 = 6 ÷ 4 = 1.5

The MAD is 1.5, I hope this helps!
