This TV/Test Grades lesson plan also includes:

Teasing relationships and trends out of data is a key mathematical skill developed through this activity for young statisticians. Taking provided data, the learners walk through the statistical process of making a hypothesis and performing tests on a data set.  In a clear and approachable way, this lesson provides tools to teach and practice basic statistical analysis of data—a great activity to introduce or shore up uncertainties in the linear regression process!

CCSS: Designed

Instructional Ideas

• Activity could be extended so that students use the steps to test their own data
• One group could do linear regression by hand (choosing points) and one with calculator regression and then compare results
Classroom Considerations

• Some students might predict a correlation between height and test scores based on age
• Home access to graphing calculators is necessary if assigned for homework
• First page scatter plot doesn't appear to belong and is not required for the lesson
Pros

• Emphasis on hypothesizing and predicting
• Clear, step-by-step instructions from hypothesis through testing data
• Teacher worksheet key provided
• Realistic and relatable data set
Cons

• No clear indication of which number in the regression is the correlation coefficient
• No post-regression analysis provided (i.e. what were your actual correlation coefficients? What does that mean?)
