Quizplus · Accepted Answer

The F-test is used to determine the statistical significance of a regression model. It assesses whether the overall regression model is a good fit for the data and whether any of the independent variables are contributing significantly to the model. The t-test and Z-test are used to determine the significance of individual coefficients in the model, while the x² test is used for goodness of fit in categorical data analysis. Therefore, the F-test is the best choice for assessing the statistical significance of a regression model.
