18, 22, 26, 11, 17, 18, 21, 24, 22, 26, 15 Calculate the mean, median, mode, and range.

11,15,17,18,18,21,22,22,24,26,26

Mean:20

Median:21

Mode:22,26,18

Range:15

Step-by-step explanation:

Mean: 18 + 22 + 26 + 11 + 17+18 + 21 + 24 + 22+26 + 15

=220 divided by 11

=20

Mode: 18, 22, 26, 11, 17, 18, 21, 24, 22, 26, 15

put it in least from greatest

11,15,17,18,18,21,22,22,24,26,26

18, 22, and 26 are the modes

Median: put it in least from greatest

11,15,17,18,18,21,22,22,24,26,26

21 is the median because its the middle number

Range: lowest to highest number and then subtract those two numbers

11 - 26 = 15

15 is the RANGE!
