PLEASE HELPPP QUESTION: What is the best measure of center for the following data set? { 2, 18,18, 20, 22, 24, 25}
A Range
B Median
C Mean
D Mode

B: Median

Step-by-step explanation:

For this data set, the best measure of center is the median because it is 20. The mean is 18.4ish, and that doesn't represent the data very well as a whole. The range is 23, which is a bit too high to represent the data, and the mode is 18, which is a bit too low to represent the data.
