The table below gives the number of hours spent watching TV last week by a sample of 24 children.

37	31	30	19	15	31
31	30	37	15	23	35
13	33	23	16	36	15
25	15	26	35	49	1

Compute each of the following summary statistics. Round your answers to the nearest tenth of an hour.

median =  hours

IQR =  hours

mean =  hours

standard deviation =  hours
range =  hours

Here are the computed summary statistics:

- **Median** = 28.0 hours
- **Interquartile Range (IQR)** = 17.8 hours
- **Mean** = 25.9 hours
- **Standard Deviation** = 10.7 hours
- **Range** = 48 hours

Would you like further clarification or additional details?

Here are five follow-up questions related to this topic:
1. How is the interquartile range (IQR) useful in understanding data spread?
2. Why might the standard deviation be more informative than the range?
3. How would the mean change if one child spent 50 hours watching TV instead of 49?
4. What does the median tell us about the distribution compared to the mean?
5. How can outliers affect the standard deviation?

**Tip:** Always check if there are any outliers when interpreting data with a high range or standard deviation.
