Consider the following data set: 8, 10, 12, 12, 14. What is the mean of the data set?a.10b.11.2c.12d.12.5

The mean of a data set is calculated by adding all the numbers in the set and then dividing by the count of numbers in the set.

Here's how you can calculate it for this data set:

Step 1: Add all the numbers together. 8 + 10 + 12 + 12 + 14 = 56

Step 2: Count the total numbers in the data set. There are 5 numbers in the data set.

Step 3: Divide the total (from Step 1) by the count (from Step 2). 56 ÷ 5 = 11.2

So, the mean of the data set is 11.2, which corresponds to option b.
