5. **Problem 5: Grouped Data Approximation**
Given ungrouped data: 10, 12, 15, 15, 18, 20, 22, estimate the mean and median and explain the process.
6. **Problem 6: Mode Interpretation**
Data: 3, 3, 4, 5, 5, 5, 6, 7
Find the mode and explain what it tells about the data.
7. **Problem 7: Median in Odd and Even Data Sets**
Data Set 1: 1, 3, 5, 7, 9
Data Set 2: 2, 4, 6, 8
Calculate the median for both and explain the difference.
8. **Problem 8: Central Tendency and Decision Making**
