Example 1:Linear regression can predict house prices based on size. For example, if the formula is: Price = 50,000 + 100 × Size (sq. ft), a 2,000 sq. ft. house would cost: Price = 50,000 + 100 × 2,000 = 250,000.

For example, the set of points in the image below fit the definition if the slope of line segment A equals the slope of line segment B. Example question: Do the points P1 = (−4, 0), P2 = (−1, 12) and P3 = (4, 32) show collinearity? Step 1: Find the slope for the ...
Example 1: Both X1 and X2 are Numerical and Uncentered This is the model you learn the most about in regression classes. In this model, the intercept is not always meaningful. Since the intercept is the mean of Y when all predictors equals zero, the mean is only useful if every X in...
Research Question and Data Company X had 10 employees take an IQ and job performance test. The resulting data -part of which are shown below- are in simple-linear-regression.sav. The main thing Company X wants to figure out is does IQ predict job performance? And -if so- how? We'll ...
