True/false the predicted score is almost always different from the actually scores

True/false the dependent variable is always continuous

Categorical vs. continuous

How is the residual or error calculated (in predicted scores)?

Give an example of both direct and indirect of a regression line

What is a useful index for the goodness of fit of the regression line?

What does a value of one indicate? what about zero?

The sum of squares of the predicted scores is called...

Why is the goodness of fit ratio given the symbol r^2
