A coach wants to know if soccer players who warm up before a game will score more points than those who don't warm up. He will break the team up into two groups and make sure each player gets equal time on the field. He will then count how many points each player makes during the game. What statistic should he study?
The standard deviation of the number of points earned by each player
The standard deviation of the number of points earned by each group
The mean number of points earned by each player
The mean number of points earned by each group

The correct answer is the last option.

Since the coach is studying the two different groups, the results will be more meaningful if the groups are compared to one another as opposed to the players. It would also make more sense to study the mean (or average) of the points scored, rather than the standard deviation (which is essentially a measure of how spread out a set of numbers are).

Answer:

The answer is The mean number of points earned by each group
