Stats teachers rejoice: Regression is here! (When does the “Eli for President” campaign begin?)

Basic

Goal: Use two expression lines (manually-entered data in a table, plus regression) to graph the points and line shown below.

Advanced

Goal: Use two expression lines (copy/pasted temperature data in a table, plus regression) to graph the points and sinusoid shown below.

Hint: For larger data sets, just copy and paste your data. Don’t add the table; Desmos will do it for you as soon as you hit “paste.”

Note: You can grab temperature data for Fresno, CA from the first tab of this spreadsheet.

Legendary

Goal: Use six expression lines to create the graph shown below. Here’s what you need:

• An image—which you can download by clicking here
• A table of manually-entered values fit to the smoke trail
• An ordered pair marking the landing ramp
• A quadratic regression
• A function defined based on the parameters generated by the quadratic regression
• A slider to animate the path of the cartoon stunt car
