WebThe coefficient of determination r^2 provides percentage variation in y (or x) which is explained by all the x (or y) variables together. Here r^2 = 0.57^2 =0.32 < 0.5 shows that the data points are highly scattered and so there is a less correlation between the self-deceptive enhancement scale and the impression management scale. WebThe well-known R 2 statistic, or the (multiple) coefficient of determination, pertains to the proportion of variance in the response variable explained by a fitted model relative to simply taking the mean of the response. In other words, it …

WebIn statistics, coefficient of determination, also termed as R 2 is a tool which determines and assesses the ability of a statistical model to explain and predict future outcomes. In other words, if we have dependent variable y and independent variable x in a model, then R 2 helps in determining the variation in y by variation x. WebA. R^2 will increase in value B. R^2 will remain the same C. R^2 will decrease Also, When adding a new independent variable to a multiple regression model, what will happen to the Adjusted Coefficient of Determination (Adj.
