Step-by-step explanation:
How to calculate the mean absolute deviation:
<u>Step 1:</u> Calculate the mean.

<u>Step 2:</u> Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.

<u>Step 3:</u> Add those deviations together.

<u>Step 4:</u> Divide the sum by the number of data points.

I would rather look at a frequency table because the exact numbers would be shown and it could tell you by how much and how frequently they’re increasing . A bar graph could do the same , but sometimes they could be grouped so it wouldn’t tell you the exact number .
Well, i am not sure if i am right, but i tried.
The prime numbers have to be consecutive, (meaning in order from least to greatest), so you find 2 prime numbers on a list, and the only two are 31 and 37 so multiply those and you should get 1147
