Question

Quizplus · Accepted Answer

R Square is also known as the coefficient of determination, which is a statistical measure that represents the proportion of the variance in the dependent variable that is predictable from the independent variable(s). It is used to assess how well the regression line represents the data and to compare different regression models. Option A is incorrect because sample correlation coefficient (also known as Pearson correlation coefficient) measures the strength and direction of the linear relationship between two variables. Option B is incorrect because the coefficient of regression represents the slope of the regression line, i.e., the change in the dependent variable per unit change in the independent variable. Option C is incorrect because the test statistic is a value calculated from a statistical test to determine if the observed data is significantly different from what we would expect if there was no effect or relationship.
