Lesson 2
Plotting Data
Let’s collect and display some data about the class.
Problem 1
In hockey, a player gets credited with a “point” in their statistics when they get an assist or goal. The table shows the number of assists and number of points for 15 hockey players after a season.

Make a scatter plot of this data. Make sure to scale and label the axes.
Problem 2
Select all the representations that are appropriate for comparing bite strength to weight for different carnivores.

Problem 3
When is it better to use a table? When is it better to use a scatter plot?
Problem 4
There are many cylinders with radius 6 meters. Let \(h\) represent the height in meters and \(V\) represent the volume in cubic meters.

Write an equation that represents the volume \(V\) as a function of the height \(h\).

Sketch the graph of the function, using 3.14 as an approximation for \(\pi\).

If you double the height of a cylinder, what happens to the volume? Explain this using the equation.

If you multiply the height of a cylinder by \(\frac 1 3\), what happens to the volume? Explain this using the graph.
