Printable math worksheet for calculating mean, median, and mode from sets of numbers.

Let's solve each problem step by step for Mean, Median, and Mode.

---

🔷 Definitions:

- Mean: Sum of all numbers ÷ number of values
- Median: Middle value when numbers are ordered (if even count, average of two middle values)
- Mode: Most frequent number (can be more than one or none)

We’ll go through each problem:

---

1. 23, 65, 56, 56, 56, 56

- Sorted: 23, 56, 56, 56, 56, 65
- Mean: (23 + 65 + 56 + 56 + 56 + 56) / 6 = (312) / 6 = 52
- Median: Middle of 6 numbers → average of 3rd and 4th: (56 + 56)/2 = 56
- Mode: 56 appears 4 times → 56

✔ Mean = 52, Median = 56, Mode = 56

2. 32, 23, 22, 33, 33, 23, 32, 23, 22

- Sorted: 22, 22, 23, 23, 23, 32, 32, 33, 33
- Mean: (22+22+23+23+23+32+32+33+33) / 9 = (243) / 9 = 27
- Median: 9 numbers → 5th is 23
- Mode: 23 appears 3 times → 23

✔ Mean = 27, Median = 23, Mode = 23

- Median: Average of 3rd and 4th: (18 + 18)/2 = 18
- Mode: 18 appears twice → 18

✔ Mean = 18, Median = 18, Mode = 18

- Median: Average of 3rd and 4th: (43 + 64)/2 = 53.5
- Mode: 43 appears twice → 43

✔ Mean ≈ 50.17, Median = 53.5, Mode = 43

---

- Sorted: 21, 21, 22, 65, 65, 65
- Mean: (21+21+22+65+65+65)/6 = (254)/6 ≈ 42.33
- Median: Average of 3rd and 4th: (22 + 65)/2 = 43.5
- Mode: 65 appears 3 times → 65

✔ Mean ≈ 42.33, Median = 43.5, Mode = 65

---

7. 22, 35, 58, 63, 75

- Sorted: 22, 35, 58, 63, 75
- Mean: (22+35+58+63+75)/5 = (253)/5 = 50.6
- Median: 5 numbers → 3rd is 58
- Mode: All appear once → No mode (or "none")

✔ Mean = 50.6, Median = 58, Mode = None
