Question

Find the Mean for 15 points

Answer 1

Hello there!

Mean is the average of a set of numbers.

To find the mean, we have to add all the numbers and divide by how many there are.

Add: 68 + 55 + 72  

Equals: 195

However, we have to find the mean of the 3 rounds in the 4th fight.

Add: 55 + 42 + 40

Equals: 137

Then, we divide it by 3.

Equals: 45.7

Next, add it to 195 since it was of 3 separate fights.

195 + 45.7 = 242.5

Lastly, divide it by 6 since there were 6 numbers in the data set.

Divide: 242.5/6

Equals: 40.42

Therefore, our mean for the 4 fights is 40.42 or 40.

There's another answer that we can get by simply adding up all the numbers and dividing it by 6.

Add: 68 + 55 + 72 + 55 + 42 + 40

Equals: 332

Then, we divide by 6.

Divide: 332/6

Equals: 55.33

So, yeah 55.33 would be the better mean then 40 since 40 makes it seem very low.
