Howards's quiz scores are below. What is the quiz average?

77, 71, 82, 79, 76, 78, 85, 83

To find Howard's quiz average, you need to calculate the mean of his scores. This is done by summing all the scores and then dividing by the total number of scores.

Given the scores:
\[ 77, 71, 82, 79, 76, 78, 85, 83 \]

1. First, add all the scores together:
\[
77 + 71 + 82 + 79 + 76 + 78 + 85 + 83 = 631
\]

2. There are 8 scores, so divide the sum by 8 to find the average:
\[
\text{Average} = \frac{631}{8} = 78.875
\]

So, Howard's quiz average is **78.875**.
