- 1
Add all the numbers, then divide by how many there are
Mean = sum of values ÷ number of values.
- 2
4
(2 + 4 + 6) ÷ 3 = 12 ÷ 3 = 4.
- 3
True
The mode is the number that appears most frequently in the data.
- 4
7
Largest = 9, smallest = 2. Range = 9 - 2 = 7.
- 5
3
Sorted: 1, 1, 3, 4, 5. The middle value is 3.
- 6
2
2 appears 3 times; every other number appears only once. The mode is 2.
- 7
Mean → Sum divided by count; Median → Middle value (sorted); Mode → Most common value; Range → Largest minus smallest
Mean = sum÷count. Median = middle (sorted). Mode = most common. Range = max-min.
- 8
6
(5 + 7 + 8 + 4 + 6) ÷ 5 = 30 ÷ 5 = 6.
- 9
6
Sorted: 2, 3, 5, 7, 8, 9. Middle two are 5 and 7. Median = (5+7) ÷ 2 = 6.
- 10
True
Largest = 20, smallest = 4. Range = 20 - 4 = 16.
