Reflection: Adjustments to Practice Understanding the Correlation Coefficient - Section 2: Investigation


One issue I have with this task is that the data is not relevant at all to the students.  If I have time, I would like to recreate this task with data that would at least have a context.  It's tricky to generate enough data sets with a variety of correlation coefficients so that students can order the graphs based on type and strength of the relationship. But I found it hard for students to connect to these random tables of numbers without any context.

Understanding the Correlation Coefficient

Unit 5: Data and Statistics
Lesson 12 of 14

Objective: SWBAT use technology to graph different data sets and use the correlation coefficient to assess the strength and direction of the relationship between two data sets.

Big Idea: Students "uncover" the meaning of the correlation coefficient (r) by graphing and examining a variety of data sets.
