Answer to Level 4 Sample Item
To get the average, first add up the numbers in the series, then divide the sum by the quantity of numbers in the series.
- (8 + 7 + 9 + 5) ÷ 5 = 5.8: Forgot to include the last 7
- 7.0 is the mode value of the numbers in the series
- (8 + 7 + 9 + 5 + 7) ÷ 5 = 7.2
Correct
- (8 + 7 + 9 + 5 + 7) ÷ 4 = 9
- 8 + 7 + 9 + 5 + 7 = 36.0: Forgot to divide by 5
