Answer 1

Okie so:

1. Put the numbers in order~

Find the middle~

11, 15, 15, 15, 16, {17}, 18, 19, 20, 22, 23

The median is 17

2. Find the middle of the first section~

11, 15, {15}, 15, 16,

The first quartile is 15

3. Find the middle of the last section~

18, 19, {20}, 22, 23

The third quartile is 20

Follow the same steps as above:

4. 8, 8, 9, 11, {13}, 17, 20, 20, 21

The answer is 13

5. 8, 8{ } 9, 11

The answer is 8.5

6. 17, 20{ } 20, 21

The answer is 20
