Question

A player had scores of 284, 192, 264, and 128 at a Yahtzee tournament. What was his mean score?

Answer 1

217

Explanation:

The mean or average is calculated by taking the sum or addition of the data points, and dividing by the number of data points. This is known as a sample of data because it is a subset of data.

In simple terms, add all the numbers up, and divide by the number of numbers.

Arithmetic mean of a sample:

`\bar{X} =\: (\sum X)/(n)`

In this case the mean or average is:

Mean = 284 + 192 + 264 + 128 / 4 = 868 / 4 = 217

Answer 2

217

Explanation:

1. "Mean" = average
2. To find the average: add the numbers together and then divide the sum by the amount of numbers added
3. 284 + 192 + 264 + 128 = 868
4. 868 ÷ 4 = 217
5. So, the average is 217

I hope this helps!
