Given that John's bowling scores were 120, 144, 143, 111 and 167, find his average score. (The rule for calculating the average of a set of scores is: Average Score = Sum of Scores/Number of Scores.)
Rule for calculating the average of a set of scores is: Average Score = Sum of Scores/Number of Scores Sum of scores = 120 + 144 + 143 + 111 + 167 = 685 Number of scores = 5 Average Score = 685/5 = 137 Thus his average score is 137.
