WebThe correlation coefficient is a statistical measure that quantifies the relationship between two variables. It can take values between -1 and +1, with a value of 0 indicating no correlation, a value of -1 indicating a perfect negative correlation (i.e., as one variable increases, the other variable decreases), and a value of +1 indicating a ... Web† A correlation coe–cient can be badly afiected by one or two outlying observations. For the ‘police expenditure’ data in Figure 2, the value of Pearson’s r is 0.514, but if the two points at the top right of this plot are removed, the correlation drops to 0.237. Always look at a scatter plot before calculating a correlation coe–cient! Webgives the standardized slope (aka ), which for a bivariate regression is identical to the Pearson r. For the data at hand, the regression equation is “cyberloafing = 57.039 - .864 consciousness.” The residuals statistics show that there no cases with a standardized residual beyond three standard deviations from zero. howard aa utility works llc
