Unformatted text preview: The slope of the regression line is symbolized by ___. b Prior to the prediction equation, we should calculate ___. r obt The point at which the regression line crosses the Yaxis, also known as the Yintercept, is symbolized by ___. a If two variables are correlated,  prediction of one variable from another is reasonable. The regression line formula is ___. Y’= bX + a The simplest way to place a regression line on a scatterplot is to predict Yvalues based on two Xvalues from the Xaxis If Pearson’s r is 1.00, prediction will be strong Multiple regression is used when we have more than one predictor in an equation In the prediction equation, which symbol is not replaced with a value until we predict a value on Y? X Which of the following is not needed when calculating error?b...
