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? 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:

Step1: Analyze data distribution

The dot - plot shows that the data is nearly symmetric.

Step2: Recall measure - of - center rules

For symmetric data, the mean is the best measure of center as it takes into account all values in the data set.

Answer:

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