4.1) 107.4
- Add: 95 + 120 + 125 + 140 + 105 + 12 + 142 + 60 + 135 + 130 = 1074
- Divide the sum by the total number of values: 1074 ÷ 10 = 107.4
4.2) 122.5.
- Let’s order them! 12, 60, 95, 105, 120, 125, 130, 135, 140, 142.
- The middle values are 120 and 125
- To find the median, we add the two middle values and divide the sum by two. (120 + 125) / 2 = 245 / 2 = 122.5.
4.3) 95
- Since we already ordered them, we can see that the third number is 95
4.4) 135
- Since we already ordered them, we can see that the seventh number is 135
4.5) 40
- 135 - 95 = 40
