Answer 1

Answer:

4

Step-by-step explanation:

Add 1+2+5+5+7=20

Then divide by the amount of numbers that there are.

There are 5 numbers.

So it would be 20 divided by 5=4

Answer 2

Answer:

MAD = 2

Step-by-step explanation:

First We'll find the mean of data

Mean = $\frac{20}{5}$

Mean = 4

Then, we'll find absolute deviation

=> |4-3| = 1

=> |4-2| = 2

=> |4-1| = 3

=> |4-1| = 3

=> |4-3| = 1

Now, taking the mean of these absolute deviations:

MAD = $\frac{1+3+3+2+1}{5}$

MAD = $\frac{10}{5}$

MAD = 2
