### What is the mean of the following data set? 10, 12, 14, 16, 20

• A.

14.4

• B.

15

• C.

15.2

A. 14.4
Explanation
The mean of a data set is calculated by adding up all the values in the set and then dividing the sum by the total number of values. In this case, the sum of the data set is 10 + 12 + 14 + 16 + 20 = 72. Since there are 5 values in the set, the mean is 72/5 = 14.4.

• C.

B. 14
Explanation
The median is the middle value in a set of numbers when they are arranged in order. In this case, the numbers are already in ascending order. There are 5 numbers in the set, so the middle value is the third number, which is 14. Therefore, 14 is the median of the set.

• A.

None

• B.

12

• C.

16

A. None
Explanation
The given set of numbers does not have a mode because no number appears more than once. In statistics, the mode refers to the value that appears most frequently in a data set. Since all the numbers in the given set appear only once, there is no number that can be considered the mode. Therefore, the correct answer is "none".
