- Set 1: 9, 4, 2, 8, 2
- Mean = (9 + 4 + 2 + 8 + 2) / 5 = 25 / 5 = 5
- Median = Sort: 2, 2, 4, 8, 9 → Middle value = 4
- Mode = Most frequent: 2 (appears twice)
- Range = Max - Min = 9 - 2 = 7
- Set 2: 9, 3, 9, 4, 4, 2, 4
- Mean = (9 + 3 + 9 + 4 + 4 + 2 + 4) / 7 = 35 / 7 = 5
- Median = Sort: 2, 3, 4, 4, 4, 9, 9 → Middle value = 4
- Mode = Most frequent: 4 (appears three times)
- Range = Max - Min = 9 - 2 = 7
- Set 3: 6, 9, 10, 9, 3, 5
- Mean = (6 + 9 + 10 + 9 + 3 + 5) / 6 = 42 / 6 = 7
- Median = Sort: 3, 5, 6, 9, 9, 10 → Middle values: 6 and 9 → Average = (6 + 9) / 2 = 7.5
- Mode = Most frequent: 9 (appears twice)
- Range = Max - Min = 10 - 3 = 7
- Set 4: 6, 9, 5, 2, 6, 5, 2
- Mean = (6 + 9 + 5 + 2 + 6 + 5 + 2) / 7 = 35 / 7 = 5
- Median = Sort: 2, 2, 5, 5, 6, 6, 9 → Middle value = 5
- Mode = Most frequent: 2, 5, and 6 (each appears twice) → Bimodal/Multimodal: 2, 5, 6
- Range = Max - Min = 9 - 2 = 7
