This is all you need to teach and have students learn Linear Regression/Regression Function/Equation. The first worksheet is a double sided worksheet that covers real world linear regression. I researched real world data and created problems that students will be interested in, rather than boring data from the textbooks. A TI-83 graphing calculator should be used, but this can be done without a graphing calculator.
The second worksheet is a single sided review worksheet that also has Literal Equations that students need to solve as extra practice.
The third is a quiz, and all the worksheets and quiz comes with answers. I even included the examples I use to teach the lesson. My whole department uses these worksheets and it does a great job in having students learn linear regression. Please, check out my other listings.
