Question

Danielle received the following scores on her essay tests:

84, 85, 83, 86, 80, 85, 86, 88, 89, 86, 83

What is the mean of her scores?

85.5
84.5
86
85

Answer 1

85

Explanation:

Think of mean as the average of a set of values. In this case, we have to find the average of Danielle's scores. To do this, add all of the values together and divide it by the number of values we have:

We have 11 scores so we will divide all of them by 11:

`(84+85+83+86+80+85+86+88+89+86+83)/(11) = (935)/(11) = 85`
