Answer 1

6.)

Mean = 58

Median = 74

Mode = 22

Range = 71

7.)

Mean = 50.4

Median = 58

Mode = 11 and/or 73

Range = 84

8.)

Mean = 59.3

Median = 58

Mode = 94,11,73

Range = 83

9.)

Mean = 43.7

Median = 45

Mode = 12

Range = 77

10.)

Mean = 41.7

Median = 43.5

Mode = 55

Range = 32

Answer 2

Answers: Use the bottom example (I only provided one since I don't want the answer to be super long, sorry) to help solve for similar problems in the future. The top part is the answer key for all problems.

6)

Mean: 58

Median: 84.5

Mode: 22

Range: 71

7)

Mean: 51

Median: 55

Mode: 55
Range: 68

8)

Mean: 50.18 (.18 is repeating) or 50.2 if needed to round.

Median: 76

Mode: 11 and 73 (They both are modes)
Range: 83

9)

Mean: 43.71 or 43.7 if the nearest tenth is needed

Median: 12

Mode: 12

Range: 77

10)

Mean: 41.66666666 (.6 is repeating) or 41.7 for rounding.
Median: 55

Mode: 55

Range: 32

Explanation:

6) Mean:

First, add all of the numbers up and divide by the amount of numbers there are.

35 + 74 + 76 + 93 + 84 + 22 + 22 = 406

Then divide 406 by 7 because there are 7 numbers.

406 ÷ 7 = 58

The mean is 58.

Median:

Take the two middle numbers and add them together and divide them by two.

76 + 93 = 169

169/2 = 84.5

Mode:

Put the numbers in order from least to greatest and find the most common number that repeats.

22, 22, 35, 74, 76, 84, 93

The mode is 22 since it repeats.

Range:

The range is the difference between the highest and lowest values in a set of numbers. Take the highest number and subtract it by the lowest number.

93 - 22 = 71

The range is 71.

I hope this helped you! :)
