A table shows a golfer score for each round of a tournament

Scorecard

Round 1: - 2

Round 2: - 6

Round 3:-7

Round 3: - 3

What was the golfers mean score per round?

Total number of rounds = 4

Score in each round, as written below:

Round 1: - 2

Round 2: - 6

Round 3:-7

Round 4: - 3

Total score across rounds = (-2) + (-6) + (-7) + (-3)

⇒ Total score across rounds = - 18

Mean score per round = Total score across rounds : Total rounds

⇒ Mean score per round = - 18 : 4

⇒ Mean score per round = - 4.5

Hence, the golfer's mean score per round was - 4.5
