The skill that covers it
What a student should be able to do
- Use a given regression equation to predict a value and interpret its slope and intercept in context.
- Compute a residual as actual minus predicted, and say what its sign means.
- Interpret a correlation coefficient r for strength and direction, and match r to a scatter plot.
- Explain why a strong correlation does not by itself show that one variable causes the other.
