3.5.6 Lesson Summary

3.5.6 • Lesson Summary

In this lesson, you learned how to:

  • Describe the strength of a relationship between two variables.
  • Use technology to find the correlation coefficient and explain what the value tells me about a linear model in everyday language.

Here are the activities that helped you reach those goals:

  • 3.5.1: Using Bivariate Data in Context
    • In this activity, you matched bivariate data with its context. You thought about whether there would be a strong correlation or not as well as whether the relationship was a positive or negative correlation.
  • 3.5.2: Finding and Using Correlation Coefficient to Interpret the Strength of Linear Relationships
    • In this activity, you used technology to find a correlation coefficient given data and used it to interpret the strength of the linear relationship in context. In addition, you interpreted the coefficients of the equation of the line of best fit and used the equation to make predictions.
    • 3.5.2: Self Check
    • 3.5.2: Additional Resources
  • 3.5.3: Using Correlation Coefficient to Describe Relationships between Two Variables
    • In this activity, you used the correlation coefficient to describe the relationship between two variables. You examined a pair of variables and a correlation coefficient to describe the relationship between the variables as strong or weak and as positive or negative.
    • 3.5.3: Self Check
    • 3.5.3: Additional Resources
  • 3.5.4: Interpreting the Correlation Coefficient
    • In this activity, you described what the sign and numerical value of the correlation coefficient tell you about the strength of the linear relationship.

After these activities, you completed the following practice:

  • 3.5.5: Practice
