1)  Compare the shapes of the dot plots.

2)  Compare the centers of the dot plots by finding the medians.

3)  Compare the spreads of the dot plots by calculating the range.

Solution

Problem 4 :

Calculate the median and range of the data in the dot plot.

Solution

Problem 5 :

The double dot plot shows the number of points scored by Sam and Daniel in 15 basketball games. What is the difference between the medians?

Solution
