Mean Worksheets (printable, online, answers, examples) - Free Printable

Of course! I'll solve each problem step by step and explain how to calculate the mean (also called the average) of a data set.

✔ What is the Mean?

The mean is calculated by:
> Adding all the numbers in the data set, then dividing by the total number of values.

Formula:
Mean = (Sum of all values) ÷ (Number of values)

Let’s solve each pair one by one.

## 🔹 First Row:

1. Data Set: `6, 9, 10, 19, 16`

- Sum = 6 + 9 + 10 + 19 + 16 = 50
- Number of values = 5
- Mean = 50 ÷ 5 = 10

✔ Answer: Mean = 10

---

2. Data Set: `4, 5, 5, 4, 2`

- Sum = 4 + 5 + 5 + 4 + 2 = 20
- Number of values = 5
- Mean = 20 ÷ 5 = 4

✔ Answer: Mean = 4

---

## 🔹 Second Row:

3. Data Set: `7, 4, 2, 5, 9, 9`

- Sum = 7 + 4 + 2 + 5 + 9 + 9 = 36
- Number of values = 6
- Mean = 36 ÷ 6 = 6

✔ Answer: Mean = 6

---

4. Data Set: `7, 8, 1, 5, 1, 2`

- Sum = 7 + 8 + 1 + 5 + 1 + 2 = 24
- Number of values = 6
- Mean = 24 ÷ 6 = 4

✔ Answer: Mean = 4

---

## 🔹 Third Row:

5. Data Set: `9, 14, 14, 8, 20`

- Sum = 9 + 14 + 14 + 8 + 20 = 65
- Number of values = 5
- Mean = 65 ÷ 5 = 13

✔ Answer: Mean = 13

---

6. Data Set: `8, 4, 4, 9, 6, 2, 9`

- Sum = 8 + 4 + 4 + 9 + 6 + 2 + 9 = 42
- Number of values = 7
- Mean = 42 ÷ 7 = 6

✔ Answer: Mean = 6

---

## 🔹 Fourth Row:

7. Data Set: `17, 14, 20, 7, 20, 6`

- Sum = 17 + 14 + 20 + 7 + 20 + 6 = 84
- Number of values = 6
- Mean = 84 ÷ 6 = 14

✔ Answer: Mean = 14

---

8. Data Set: `7, 1, 3, 3, 1, 9`

- Sum = 7 + 1 + 3 + 3 + 1 + 9 = 24
- Number of values = 6
- Mean = 24 ÷ 6 = 4

✔ Answer: Mean = 4

---

## 🔹 Fifth Row:

9. Data Set: `7, 1, 3, 3, 1, 9`

*(This is the same as #8 above — probably a repeat or typo)*

- Sum = 24
- Count = 6
- Mean = 24 ÷ 6 = 4

✔ Answer: Mean = 4

---

10. Data Set: `9, 6, 2, 3, 5`

- Sum = 9 + 6 + 2 + 3 + 5 = 25
- Number of values = 5
- Mean = 25 ÷ 5 = 5

✔ Answer: Mean = 5

---

## 📋 Final Answers Summary:

| Data Set | Mean |
|---------------------------|------|
| 6, 9, 10, 19, 16 | 10 |
| 4, 5, 5, 4, 2 | 4 |
| 7, 4, 2, 5, 9, 9 | 6 |
| 7, 8, 1, 5, 1, 2 | 4 |
| 9, 14, 14, 8, 20 | 13 |
| 8, 4, 4, 9, 6, 2, 9 | 6 |
| 17, 14, 20, 7, 20, 6 | 14 |
| 7, 1, 3, 3, 1, 9 | 4 |
| 7, 1, 3, 3, 1, 9 | 4 |
| 9, 6, 2, 3, 5 | 5 |
