Verified answer

MEAN- add all the numbers then devide by the amount of numbers

MEDIAN- order the set of numbers, the median is the middle number

MODE- the most common number

SOLUTIONS:

1. )

MEAN:

= 29+34+37+22+15+38+40

=215/7

= 30.71

MEDIAN:

=15, 22, 29, 34, 37, 38, 40

= 34

MODE:

= No mode

2)

MEAN:

=5+6+7+7+9+9+9+10+14+16+20

= 112/11

= 10.18

MEDIAN:

= 5, 6, 7, 7, 9, 9, 9, 10, 14, 16, 20

= 9

MODE:

= 5, 6, 7, 7, 9, 9, 9, 10, 14, 16, 20

most common number = 9

3)

MEAN:

= 82+61+93+56+34+57+92+53+57

=585/9

=65

MEDIAN:

= 34, 53, 56, 57, 57, 61, 82, 92, 93

= 57

MODE:

=34, 53, 56, 57, 57, 61, 82, 92, 93

most common number= 57

4.)

MEAN:

= 26+32+12+18+11+12+15+18+21

=165/9

= 18.33

MEDIAN:

=11, 12, 12, 15, 18, 18, 18, 21, 26, 32

= 18

MODE:

=11, 12, 12, 15, 18, 18, 18, 21, 26, 32

most common number= 18

5.)

MEAN:

= 25+33+35+45+34+26+29+35+38+40

= 340/10

= 34

MEDIAN:

= 25, 26, 29, 33, 34, 35, 35, 38, 40, 45

= 34,35

= 34+35

= 69/2

= 34.5

MODE:

=25, 26, 29, 33, 34, 35, 35, 38, 40, 45

most common number= 35
