Question

Brock scored the following number of goals in her soccer games: 2, 3, 1, 0, 3, 2,1, 2. What is the mean of the data?

Answer 1

`1.75`

Explanation:

The formula you need is

`color(blue)("mean" = (sum("values"))/"number of values")`

In this case, the values represent the number of goals and the number of values represents the number of matches.

Notice that Brock played a total of `8` football games, but that he only scored in `7` of those matches. However, you still need to take into account the value `0` and count it for the total number of matches.

Plug in your values to find

`"mean" = (2 + 3 + 1 + 0 + 3 + 2 + 1 + 2)/8`

`"mean" = 14/8 = color(green)("1.75")`
