In reality, we are going to let Minitab calculate the F* statistic and the P-value for us. The P-value is determined by comparing F* to an F distribution with 1 numerator degree of freedom and n-2 denominator degrees of freedom. In this article, you will see the steps needed to calculate the mean for any data set in Minitab. \(MSE=\dfrac\).Īs always, the P-value is obtained by answering the question: "What is the probability that we’d get an F* statistic as large as we did if the null hypothesis is true?" One useful technology tool for calculations and statistics is Minitab. ![]() We already know the " mean square error ( MSE)" is defined as: Help A complete Help file is incorporated in Minitab, which provides you with instructions, examples with interpretations, overviews and detailed explanations, troubleshooting tips, formulas, references, and a. Let's tackle a few more columns of the analysis of variance table, namely the " mean square" column, labeled MS, and the F-statistic column labeled F. Minitab 20 Support - Getting Started is a concise guide designed to quickly get you familiar with using Minitab Statistical Software. The sums of squares add up: SSTO = SSR SSE.And the degrees of freedom add up: 1 47 = 48. The degrees of freedom associated with SSE is n-2 = 49-2 = 47. Let's tackle a few more columns of the analysis of variance table, namely the ' mean square ' column, labeled MS, and the F -statistic column labeled F. ![]() The sums of squares add up: SSTO SSR SSE. And the degrees of freedom add up: 1 47 48. The degrees of freedom associated with SSTO is n-1 = 49-1 = 48. The degrees of freedom associated with SSE is n -2 49-2 47. The degrees of freedom associated with SSR will always be 1 for the simple linear regression model. ![]() Recall that there were 49 states in the data set.
