1. **State the problem:** Find the median and mean of the data set: 30, 7, 2, 10, 19. 2. **Median:** The median is the middle value when the data is ordered from smallest to largest. 3. Order the data: 2, 7, 10, 19, 30. 4. Since there are 5 numbers (odd count), the median is the middle one: the 3rd number. 5. Median = 10. 6. **Mean:** The mean is the sum of all values divided by the number of values. 7. Sum the data: $$30 + 7 + 2 + 10 + 19 = 68$$. 8. Number of data points: 5. 9. Calculate mean: $$\frac{68}{5}$$. 10. Show cancellation step: $$\frac{\cancel{68}}{\cancel{5}}$$ (no common factors to cancel). 11. Mean = $$13.6$$. **Final answers:** Median = 10, Mean = 13.6.
