# Ch 7: Linear Relationships

Further develop your understanding of linear relationships and models in math by referring to the video and text lessons in this chapter. Use this resource to support your math class studies or to help you prepare for year-end assessment or a college entrance exams.

## Linear Relationships - Chapter Summary

From coefficients to residuals, this chapter covers everything about linear relationships that you would need to know at the secondary or college level. You will have the opportunity to review definitions and formulas used in this area of statistics and mathematics.

How do you interpret slope? What is linear regression? Why is understanding linear relationships important in statistics? These are some of the topics you can expect to explore in this chapter. Once you are finished with these lessons, you should be able to:

• Differentiate between linear and nonlinear relationships and transform nonlinear data
• Evaluate linear models and calculate linear regression
• Define line of best fit
• Analyze residuals and interpret slope and intercept
• Determine the relationship between two variables
• Describe how to compute coefficient of determination
• Understand the formula to determine the Pearson correlation coefficient
• Use data to interpret linear relationships

Complex data is explained in simple terms by expert instructors in this field and students can easily contact instructors if they are having difficulty with any topic. Lessons are accessible 24/7 and video lesson transcripts are printable for quick reference. Self-assessment quizzes measure how much has been retained from each lesson and one's readiness in moving from one topic to the next.
