Question
**Calculating the Standard Deviation by Hand**

A student in a nutrition class wrote down the number of calories he ate for lunch for 5 days. His results are in the table below:

| Number of Calories |
|--------------------|
| 200                |
| 600                |
| 475                |
| 400                |
| 425                |

The mean number of calories for the data set is 420. Use the mean to complete the table below and find the standard deviation.

**Do not round any of your results except the final standard deviation.**

*Note: The difference from the mean is calculated as* \[ \text{data value} - \text{mean} \]. *It may be negative.*

| Number of Calories | Difference from the Mean | Squared Difference from the Mean |
|--------------------|--------------------------|----------------------------------|
| 200                |                          |                                  |
| 600                |                          |                                  |
| 475                |                          |                                  |
| 400                |                          |                                  |
| 425                |                          |                                  |
