Match the mean median mode and range for the data set below 16 9 20 10 12 6 8 15

12 is mean     11 is median     range is 14

Step-by-step explanation:

For the Mean

Add all the numbers up

16 + 9 + 20 + 10 =55

12 + 6 + 8 + 15 = 41

55 + 41 = 96

There are 8 numbers so we divide by 8

96/8 = 12

Range is Smallest number minus biggest so 20 - 6 = 14

Mean: 12

Median: 11

Mode: No Mode

Range: 14

Step-by-step explanation:

Mean:

- To calculate the mean, add up all the numbers, and divide by the number of numbers there are.

16 + 9 + 20 + 10 + 12 + 6 + 8 + 15 = 96

96 divide by 8 = 12

Median:

- Order the numbers from least to greatest, and find the middle number!

6, 8, 9, 10, 12, 15, 16, 20

Since there is NO middle number, because there are 8 numbers, add the two numbers (10 + 12), and divide by 2.

10 + 12 = 22

22 divided by 2 = 11

Mode:

The mode is the number that appears most often. Since NO number appears more than once, there is no mode.

Range:

- The range is the difference between the highest number and the lowest.

Highest Number: 20

Lowest Number: 6

20 - 6 = 14
