A mini-golf course is determining the par score for each of its holes. The dot plot shows the number of strokes required to place a ball in the ninth hole for a sample of 31 players.

A number line going from 1 to 9. 2 dots are above 1. 3 dots are above 2. 4 dots are above 3. 5 dots are above 4. 5 dots are above 5. 3 dots are above 6. 2 dots are above 7. 0 dots are above 8. 1 dot is above 9.
Which measure of center is best to use to determine the expected number of strokes required for the ninth hole?

The mean is the best choice because the data is nearly symmetrical.
The median is the best choice because data is clustered.
The mean is the best choice because the data is skewed to the right.
The median is the best choice because the data is skewed to the left.
