It seems you've uploaded two images. One shows a survey question about study hours per week, and the other demonstrates how to calculate the **standard deviation** with a list of values and the formula.

Would you like assistance with solving a standard deviation problem or interpreting the images further? If you're working on the standard deviation, I can walk you through how to calculate it using the provided values.

Feel free to ask if you need details, and here are some follow-up questions that might help:

1. Would you like to compute the standard deviation for the values provided in the second image?
2. Are you familiar with each step involved in finding the standard deviation?
3. Do you need help with calculating the mean (\(\overline{x}\)) for the data?
4. Should I explain how to interpret the result of the standard deviation?
5. Do you want to relate the study hours per week to any statistical measures?

**Tip:** The smaller the standard deviation, the closer the data points are to the mean. A large standard deviation indicates more spread out data.

Learn how to calculate the standard deviation for a set of data using the formula √[Σ(x - x̄)² / (n - 1)]. This step-by-step guide demonstrates using an example dataset and covers key statistical concepts like the mean and variance. Suitable for Grades 9-12.
