Printable math worksheet for finding the mean of data sets.

To find the mean (average) of a set of numbers, you follow two simple steps:
1. Add all the numbers together to get the Total.
2. Divide that total by how many numbers there are.

Here are the solutions for each question on the sheet:

2) 5, 4, 3
* Total: $5 + 4 + 3 = 12$
* Count: 3 numbers
* Mean: $12 \div 3 = 4$

3) 14, 10, 12
* Total: $14 + 10 + 12 = 36$
* Count: 3 numbers
* Mean: $36 \div 3 = 12$

4) 2, 10, 3
* Total: $2 + 10 + 3 = 15$
* Count: 3 numbers
* Mean: $15 \div 3 = 5$

5) 8, 0, 10
* Total: $8 + 0 + 10 = 18$
* Count: 3 numbers
* Mean: $18 \div 3 = 6$

6) 4, 1, 4
* Total: $4 + 1 + 4 = 9$
* Count: 3 numbers
* Mean: $9 \div 3 = 3$

7) 12, 7, 2
* Total: $12 + 7 + 2 = 21$
* Count: 3 numbers
* Mean: $21 \div 3 = 7$

8) 2, 5, 11
* Total: $2 + 5 + 11 = 18$
* Count: 3 numbers
* Mean: $18 \div 3 = 6$

9) 14, 3, 7
* Total: $14 + 3 + 7 = 24$
* Count: 3 numbers
* Mean: $24 \div 3 = 8$

10) 20, 3, 4
* Total: $20 + 3 + 4 = 27$
* Count: 3 numbers
* Mean: $27 \div 3 = 9$

11) 2, 5, 1, 0
* Total: $2 + 5 + 1 + 0 = 8$
* Count: 4 numbers
* Mean: $8 \div 4 = 2$

12) 4, 1, 3, 4
* Total: $4 + 1 + 3 + 4 = 12$
* Count: 4 numbers
* Mean: $12 \div 4 = 3$

13) 7, 3, 0, 10
* Total: $7 + 3 + 0 + 10 = 20$
* Count: 4 numbers
* Mean: $20 \div 4 = 5$

14) 1, 2, 3, 2
* Total: $1 + 2 + 3 + 2 = 8$
* Count: 4 numbers
* Mean: $8 \div 4 = 2$

15) 10, 2, 1, 3
* Total: $10 + 2 + 1 + 3 = 16$
* Count: 4 numbers
* Mean: $16 \div 4 = 4$

16) 10, 20, 10, 40
* Total: $10 + 20 + 10 + 40 = 80$
* Count: 4 numbers
* Mean: $80 \div 4 = 20$

Final Answer:
2) Total: 12, Mean: 4
3) Total: 36, Mean: 12
4) Total: 15, Mean: 5
5) Total: 18, Mean: 6
6) Total: 9, Mean: 3
7) Total: 21, Mean: 7
8) Total: 18, Mean: 6
9) Total: 24, Mean: 8
10) Total: 27, Mean: 9
11) Total: 8, Mean: 2
12) Total: 12, Mean: 3
13) Total: 20, Mean: 5
14) Total: 8, Mean: 2
15) Total: 16, Mean: 4
16) Total: 80, Mean: 20
