Question

The final exam scores in a statistics class were as follows: 90, 70, 63, 98, 95, 32, 54, 89, 84, 80, 68, 71, 77, 71, 83 Find the mean quiz score

Answer 1

75

Explanation:

The mean [average] of a set of data is "the sum of all the numbers divided by the number of numbers".

How many numbers are in the data set?

15

So we simply add all of them up and divide by sum by 15. Doing so gives us the mean:

Mean =
`(90+70+63+98+95+32+54+89+84+80+68+71+77+71+83)/(15)=(1125)/(15)=75`

The mean is 75
