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 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. 1 2 3 4 5 6 7 8 9 number of strokes
Answer
Answer:
The mean is the best choice because the data is nearly symmetrical.
Explanation:
Step1: Analyze dot - plot shape
The dot - plot appears symmetric.
Step2: Recall measure of center properties
For symmetric data, mean is a good measure.
Step3: Eliminate incorrect options
Data is not clustered, skewed left or right. So, mean is the best choice.
