Question

The following graph plots the batting averages of 29 players of a baseball team against the weekly time (in hours) they spend in batting practice.

Which statement is a reasonable conclusion that may be drawn from the graph?

Practice and batting average have no direct relationship.
The best batter has an average of 0.33.
Batting practice increases batting averages.
The worst batter has an average of 0.

Answer 1

Batting practice increases batting averages.

Explanation:

By looking at the graph, we clearly see a trend, almost a straight line (if you regroup the points a bit) going up.

So, it's clear that batting practice increases batting averages; they're directly related. The more a player practices at bat, the better will be his average.

Answers B and D (best and worst batters) are not proved at all by the graph, since there's data higher than those two cases.
