Question

Consider the following data. 9,−2,9,9,−2,−2,14 Step 1 of 3 : Determine the mean of the given data.

Answer 1

To find the mean of a given set of data, you divide the sum of all the values and divide it by the number of values.

`9,-2,9,9,-2,-2,14`

`9+-2+9+9+-2+-2+14\\=35`

There are a total of 7 values that are given. So, to find the mean, we simply must divide 35(the sum of all values) by 7(the number of values).

`35/7=5`

Therefore, the mean of our given set of data is 5.
