Answered by TooFree

Step 1: Arrange them in ascending order (smallest to biggest):

2, 3, 4, 7, 7, 8, 9, 12, 15, 17, 18, 19, 20

Step 2: Find the mean:

Mean = Sum ÷ number of numbers

Sum = 2 + 3 + 4 + 7 + 7 + 8 + 9 + 12 + 15 + 17 + 18 + 19 + 20 = 141

Mean = 141 ÷ 13 = 10.85 (nearest hundredth)

Mean = 10.85

Step 3: Find the medium:

There are 13 numbers, the middle number is the 7th number

7th number = 9

Answer: Medium = 9

Step 4: Find the mode:

Mode = the number that appears the most often.

Mode = 7 (which appears twice)

Answer: Mode = 7
