Question

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. which measure of center is best to use to determine the expected number of strokes required for the ninth hole? ninth hole strokes number of strokes 1 2 3 4 5 6 7 8 9 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.

Explanation:

When data is nearly symmetrical, the mean is a good measure of central tendency as it takes into account all values in the data - set. Looking at the dot - plot, the data appears to be nearly symmetrical. The median is more appropriate when data is skewed or has outliers.

Answer:

The mean is the best choice because the data is nearly symmetrical.
