7. Write the equation of the regression line using. (You write this, but put in your computed values for a and b. The hat on the y means that this is a predicted value for y, which isn’t necessarily the same as a value for y in the data itself.) 8. Use the equation of the regression line to …

Regression Equation. Just as simple linear regression defines a line in the (x,y) plane, the two variable multiple linear regression model Y = a + b1x1 + b2x2 + e is the equation of a plane in the (x1, x2, Y) space. In this model, b1 is slope of the plane in the (x1, Y) plane and b2 is slope of the plane in the (x2, Y) plane.

Equation for Least Squares (Regression) Line = denotes the slope. The slope in the equation equals the amount that changes when x increases by one unit. denotes the y-intercept. The y-intercept is the predicted value of y when x=0. The y-intercept may not have any interpretive value. If the answer to either of the two questions below is no, we ...

Hypothesized Regression Equation/Model and the Estimating Equation. When we follow the steps in regression (coming up shortly) we come up with two forms of our regression line or model. The first is a hypothesized model (following the general format of steps to research design) From a previous example, on Effort and Performance in 520, we had ...

Measurement and Linear Regression
Students will plot the data, find the equation of the regression line and interpret the slope and y-intercept within the context of the exploration. Slope as a rate of change will be emphasized. This activity is intended as a follow-up to linear relationships and regression.
