What is the mean of the numbers 5, 10, and 6?

• 6

• 7

• 8

• 9

How do you find the median in a data set with an odd number of values?

• Subtract the smallest number from the largest

• Find the middle number after sorting

• Add all numbers and divide by the number of values

• Identify the most frequent number

What is the median of the data set 3, 5, 6, 9, 10, 11, 12?
