MATH 534 Week 6 Discussion Regression Analysis (Keller) Here,wearetalkingaboutregressionanalysis.Regressionanalysisreferstoa statisticalmethodofmodelingtherelationshipsbetweendifferentvariables(dependentand independent). It is used to describe and analyze relationships between data. Also,the regression analysis is used to make predictions, the relationships between databeingusedasabasis forforecastinganddesigningapredictionmodel.

3 If the correlation coefficient between variables X and Y is roughly zero, then 6 In the equation y = m x + b, which represents a straight lime, b is the 7 If the relationship between y and x is given by the equation y = 1.57 − 0.0407 x, the slope coefficient 0.0407 means this for every unit increas
