Using your calculator, find the range and standard deviation, round to two decimals places:
The table below gives the number of hours spent watching TV last week by a sample of 24 children.
44 45 79 38 46 81
31 80 78 61 35 39
57 50 28 85 86 79
21 35 33 26 97 17
Range =
Standard Deviation =

It seems like I can’t do more advanced data analysis right now. Please try again later. However, you can manually compute the range and standard deviation by following these steps:

### To find the **Range**:
1. Identify the maximum and minimum values from the data.
2. Subtract the minimum value from the maximum value.

### To find the **Standard Deviation**:
1. Find the mean (average) of the data.
2. Subtract the mean from each data point and square the result.
3. Find the average of those squared differences.
4. Take the square root of that average.

Here are some follow-up questions to consider:
1. What is the purpose of calculating the range in statistics?
2. How does the standard deviation relate to data variability?
3. What happens to standard deviation if there are outliers in the data?
4. Can you calculate the variance from standard deviation?
5. What are other measures of spread besides range and standard deviation?

**Tip:** In statistics, standard deviation is crucial because it gives insight into how much the data varies from the mean.
