Day 146 - Lesson 10.5

Learning Targets
  • State hypotheses for a test about the relationship between two quantitative variables.

  • Check conditions for a test about the relationship between two quantitative variables.

  • Calculate the test statistic and P-value for a test about the relationship between two quantitative variables given summary statistics.

We will spend two days on this lesson since the concept is a bit more complex than the other significance tests.  Thinking about testing a slope is a bit of a jump for students.  In order to make this concept less abstract, we are going to do some hands on simulation.  This is a little time consuming so we will do all of this on day 1 and on day 2 we will start forming the significance test.

Teaching Tip:

Students have done simulations similar to this before.  This lesson reminds me a bit of the first simulation dotplot we made in chapter 3 and also of the free throw simulations in chapter 8.
