Math worksheet for calculating mean, median, and mode with 12 practice problems.

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

- 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
