Answer:

Explanation:

The first thing you need to do is order the numbers from least to greatest.

This would be:

6, 7, 7, 7, 8, 9, 10, 10

To find the Mean, add up all of your numbers and then divide by how many numbers there are altogether. In other words, it is the sum divided by the count.

In this case, it would be:

6+7+7+7+8+9+10+10

= 64, your MEAN

To find Median, you basically need the middle number.

For example:

a, b, c, d, e

c would be your Median because it is in the middle.

Other cases like if you had an only 4 letters or numbers you would have to divide it.

For example:

1, 2, 3, 4

The median would be 2 and 3. BUUUTTT because you can only have 1, you have to do 2.5, since 2.5 is the number inbetwen 2 and 3.

To find Mode, you basicly

see what number appears more.

In your case it would be 7. It appears 3 times compared to the 1 and two times the other numbers appear.

Hope that helps!! :)
