What is the average of the weekly satisfaction scores 80, 82, 85, and 84?

Explanation:
To find the average, add all the values and divide by how many values there are. Add the four scores: 80 + 82 + 85 + 84 = 331. Divide by 4, since there are four weeks: 331 ÷ 4 = 82.75. So the average weekly satisfaction is 82.75, a value between 82 and 83. This exact mean isn’t 82.5 or 83 because those would come from different totals or rounding; the precise average of these four numbers is 82.75.
