The population standard deviation of the given data is approximately 3.35.

Would you like a detailed explanation of the steps involved?

Here are five related questions to explore further:

1. How do you calculate the variance of a population?
2. What's the difference between population and sample standard deviation?
3. How does standard deviation help in understanding data distribution?
4. How can we interpret a low vs. high standard deviation in practical terms?
5. Can standard deviation be used to identify outliers in a dataset?

Tip: Population standard deviation uses the total number of data points, whereas sample standard deviation divides by one less than the number of data points.
