The question is: "Why is the standard deviation used more frequently than the variance?"

The options are:

A. The standard deviation requires less entries from the data set.
B. The units of variance are squared. Its units are meaningless.
C. The standard deviation is easier to compute.

The correct answer is **B.** The units of variance are squared, which makes them less intuitive or harder to interpret compared to the original data's units. Standard deviation, on the other hand, is in the same units as the data, making it more meaningful and easier to understand in practical applications.

Here are 5 related questions for further exploration:
1. What is the mathematical relationship between variance and standard deviation?
2. How is variance calculated for a data set?
3. Can standard deviation ever be larger than the variance?
4. What are some common uses of standard deviation in real-world data analysis?
5. How does the interpretation of standard deviation differ from variance?

**Tip:** Remember that variance is the square of the standard deviation, and its units reflect this squared nature, which is why standard deviation is often more practical for comparison and interpretation.
