1. **State the problem:** We need to find the range of the dataset: 15, 22, 8, 17, 30. 2. **Formula for range:** The range of a dataset is given by the difference between the maximum and minimum values: $$\text{Range} = \text{Maximum value} - \text{Minimum value}$$ 3. **Identify the maximum and minimum values:** - Maximum value = 30 - Minimum value = 8 4. **Calculate the range:** $$\text{Range} = 30 - 8 = 22$$ 5. **Conclusion:** The range of the dataset is 22.
