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. ninth hole strokes number of strokes 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.

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 is nearly symmetrical around the center values. The median is more appropriate when data is skewed or has outliers. Since the data here is not skewed and is nearly symmetrical, the mean is the best choice.

Answer:

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