Mean.
Median.
Range.
Standard deviation.

3. Calculate the mode for the number of bathrooms.

4. Produce two frequency distributions and histogramsâ?"one for homes with pools and one for homes withoutâ?"showing the number of homes by niceness rating (Column E). What do these two distributions tell you about the relationship between niceness rating and the presence of a pool?

5. Produce a histogram that shows the number of houses by price range, in increments of $50,000 (for example, $0-$50,000, $50,001-$ 100,000, and so on).

6. Produce a scatter plot showing the relationship between price and home size.

7. Produce a scatter plot relating the number of bathrooms to price. Explain why this plot has a bar-like pattern.
