Compute the linear regression equation.

Calculate the coefficient of determination.

Calculate the coefficient of alienation.

Predict the Y score for someone who obtains an X score of 6.

If the prediction is wrong, by how much do you expect it to be wrong?

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
