Linear Regression

the best summary of the linear relationship between two variables


r score indicating a significant relationship

Regression Line

reflects the "perfect" version of the linear relationship

Predicted value; mean

regression line uses the ---- of Y at each X instead of the ---- of Y

Regression equation

produces the predicted value of Y at each X

Y' = bX + a

Regression equation

slope and y intercept

two components of the regression equation

slope (b)

summarizes the rate at which Y values change as X increases and the direction of that change

rate; direction of change

slope summarizes the --- at which Y values change as X increases and the ----

Y intercept (a)

the starting point from which the Y scores change; point at which regression line would intercept the Y axis

fall outside of the range of variables tested

cannot make predictions for scores that ----- by using the regression equation
