Web“constant.” The slope is given in the “B” column to the right of the name of the X variable. SPSS also gives 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.” WebNov 4, 2024 · A standard t-test against the null hypothesis $\beta_3=0$ is a test of the slope difference. You might look for a deeper treatment of this under the rubrics of regression discontinuity designs (usually when the predictor is not time), or changepoint analysis/interrupted time series analysis (when the predictor is time).
