2 1. Which of the variables are categorical?

2. Which of the variables are quantitative?

3. Create a pie chart for PED usage.

4. Create a segmented bar chart for nationality.

3 5. Create a dot plot to show the spread of the average speed.

6. Create a box and whisker plot. Show if there are any outliers.

7. Compare the dot plot to the box and whisker plot. What do you notice?

4 8. Construct, carefully label, and describe a histogram showing average speed.

5 9. Find the following statistics for average speed in km/hr.

Count n = Meanx ¯ = Standard deviation Sx = Minimum = First Quartile Q1 = Median = Third Quartile Q3 = Maximum =

10. Convert the speeds to miles per hour (1 km = 0.621 miles). Find the following statistics again. What changed? What stayed the same?

Count n = Meanx ¯ = Standard deviation Sx = Minimum = First Quartile Q1 = Median = Third Quartile Q3 = Maximum =
