The Chi-Square Goodness-of-Fit Test can test if the proportions for all groups are equal.

. Choose the distribution that best fits your data and is. Using Minitab to run a Goodnessoffit Test 1. Click on Stat choose Tables and then Chisquare Goodness of Fit Test One Variable.

Minitab performs goodness-of-fit tests on your data for a variety of distributions and estimates their parameters. It can also be used to test if the proportions for groups are equal to specific values. Minitab checks to see if the observed counts differ from the global distribution.

Interpret a goodness-of-fit test and choose a distribution. Exact p-values can be requested for small sample sizes when no parameters are estimated. In Minitab go to Stat Tables Chi-Square Goodness-of-Fit Test One Variable.

Enter Color in Category names. Learn more about Minitab 19. In this post well explore the R-squared R 2 statistic some of its limitations and uncover some surprises along the way.

Using Minitab Express to get the test statistic and p-value for a Chi-Square Goodness of Fit test when the expected distribution is uniform. Minitab performs goodness-of-fit tests on your data for a variety of distributions and estimates their parameters. Chi-Square Goodness-of-Fit Test 1 Variable.

As shown above both the plot and the p-value for the Weibull distribution goodness-of-fit test suggest that it is a good fit for this data. With interval data Minitab provides only the MIL-Hdbk-189 test. Learn How to Analyse Your Data More Effectively at Anytime With Minitab Trainer Online.

To help you out Minitab statistical software presents a variety of goodness-of-fit statistics. N is the total sample size. The more categories you have in your study the more degrees of freedom you have.

Use Minitabs Stat Tables Chi-Square Goodness-of-Fit Test One Variable when you have just one variable. In this case a p-value below 05 on the Goodness-of-Fit test indicates that a distribution is not a good fit for the data. For a significance level α chosen before you conduct your test a p-value P less than α indicates that the data do not follow that distribution.
