Given data set:

6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8

Find the mean, median, and mode of the data set.

see below

Step-by-step explanation:

6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8

First put the numbers in order from smallest to largest

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

The mean is adding all the numbers and dividing by the number of numbers

(1+1 + 2+6+6 + 7 + 7 + 7 + 8 + 9 + 12) / 11

66/1 = 6

The mean is 6

The median is the middle

There are 11 terms

11/5 = 5.5 so 6 is the middle number

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

7 is the median

Mode is the most often

7 appears three times so it is the mode
