Compare Two Sets of Data Within a Single Data Display

What is a back to back stem and leaf plot used for?

• To display data in a visual format.

• To analyze trends in a single set of data.

• To calculate the mean of a data set.

• To compare two sets of data

When would you use a back to back stem and leaf plot instead of a regular stem and leaf plot?

• When displaying data with a large range of values.

• When visualizing data with outliers.

• When comparing two sets of data side by side.

• When comparing data from different time periods.

What are the advantages of using a split stem and leaf plot?

• The advantages of using a split stem and leaf plot include easier comparison of data sets, identification of patterns or trends, clearer representation of data distribution, and more detailed analysis.

• The split stem and leaf plot is time-consuming and tedious to create.

• Using a split stem and leaf plot can lead to misinterpretation of data.

• Split stem and leaf plots are not suitable for large data sets.

• The distribution of guesses for male students is skewed to the left, and the distribution of guesses for female students is skewed to the right.

• The distribution of guesses for male students is skewed to the right, and the distribution of guesses for female students is skewed to the left.

• The distributions of guesses for male and female students are both skewed to the right.

• The distributions of guesses for male and female students are both skewed to the left.

• The distributions of guesses for male and female students are both symmetric.

A car rental agency has two locations in a city. The boxplots below summarize the miles driven for one day of single-day car rentals at each location.

Based on the boxplots, which statement provides the best comparison of the two locations?

• The number of single-day rentals is greater for location A than for location B.

• The number of single-day rentals is less for location A than for location B.

• Compared with location A, the miles driven for location B display more variability, and the median is greater.

• Compared with location A, the miles driven for location B display less variability, and the median is greater.

• Compared with location A, the miles driven for location B display less variability, and the median is about the same.
