Study GuideStatistics–Bivariate Relationships1.Quiz: Simple Linear Regression1. QuestionThe coefficients of the least squares regression line are determined by minimizing the sum of thesquares of the:Answer Choices• x-coordinates• y-coordinates• residualsCorrect AnswerresidualsWhy This Is CorrectLeast squares regression chooses the line that makes thevertical errors(residuals) as small aspossible overall by minimizing thesum of squared residuals.2. QuestionA residual is computed as:Answer Choices• a y-coordinate from the data minus a y-coordinate predicted by the line• a y-coordinate predicted by the line minus a y-coordinate from the data• an x-coordinate from the data minus an x-coordinate predicted by the linePreview Mode
