Hi there! Hopefully this helps!

Question A answer: 2.
To find the median, you simply need to order the set from lowest to highest and finding the exact middle. So it should look like this:
0, 1, 2, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.

Question B answer: 2
To find the mean, you have to add all of the numbers together and then you have to divide by the number of items in the set. There are 5 numbers in the set so it should look like this:
0 + 1 + 2 + 3 + 4 = 10.
Since there 5 numbers in the set, we need to divide by 5.
10 / 5 = 2.
Therefore, 2 is also the answer to Question B.
