The extracted text contains detailed survey data, including several percentage responses for each statement, as well as columns for total responses, mean, median, mode, and range.

To calculate the standard deviation, I will focus on the "mean" column for each statement. I will extract these values from the text and proceed to calculate the standard deviation.

Let's proceed with extracting the mean values and compute the standard deviation.It seems like I can’t do more advanced data analysis right now. Please try again later. If you need any other help or have questions, feel free to ask!

Here are some related questions you might consider:

1. How do you calculate standard deviation from a given set of data?
2. What are the benefits of calculating mean and standard deviation together?
3. How does standard deviation help in evaluating survey data?
4. What other statistical measures can be useful in analyzing survey results?
5. How can median and mode complement the analysis of the mean?

Tip: Standard deviation helps you understand the spread of data points in a set, giving insight into variability beyond just the average.
