• Y - test score (test score is name of variable on Y-axis)
• r = 0.821

8. Which variable is the independent variable?

9. Which variable is the dependent variable?

10. Based on chart for interpreting the correlation coefficient value in the video, how would you interpret the r value: 0.821?

11. What does the r value (0.821) suggest about the correlation between time spent studying and test score?

12. What is the name given to R²?

13 How do you calculate R²?

14. For the 0.821 r value, calculate R².

15. Convert your R²value to a percentage.

16. Interpret the R²that you calculated in question 15. In other words, what does the R²value tell us about the two variables - time spent studying and test score - for this assignment?
