HSS.ID.C.8: Compute (using technology) and interpret the correlation coefficient of a linear fit.
What you'll learn
- State that the correlation coefficient r measures the strength and direction of a linear association on a scale from -1 to +1
- Compute r using a calculator or spreadsheet
- Interpret the sign of r as direction and the magnitude as strength, and match r values to scatter-plot appearance
- Recognize that r measures only linear association and does not establish causation
