1. Which dog-walker did you select? Circle one.

Comparing the Morning and Afternoon Groups

2. Create frequency tables to represent the morning and afternoon dogs as two sets of data. Group the weights into classes that range 10 pounds.

3. What is the median of the morning (AM) group? What is the median of the afternoon (PM) group?

4. What is the first quartile (Q1) of the morning (AM) group? What is the first quartile (Q1) of the afternoon (PM) group?

5. What is the third quartile (Q3) of the morning (AM) group? What is the third quartile (Q3) of the afternoon (PM) group?

6. Create a comparative box plot for the morning and afternoon dogs, and label each with its five-number summary.

7. What is the interquartile range (IQR) of the morning (AM) group? What is the interquartile range (IQR) of the afternoon (PM) group?

8. The average weights of the dogs are the same for the morning and afternoon groups. But based on your comparative box plot and the IQRs of the two groups, which group of the dogs do you think would be easier to walk as one group?
