To perform a chi-square goodness-of-fit test in Minitab using summarized data we first need to enter the data into the worksheet. Minitab also has the ability to conduct a chi-square goodness-of-fit test when the hypothesized population proportions are not all equal. Minitab uses the Anderson-Darling statistic to calculate the p-value.

Analysis for Fig 86. In order to interpret a goodness-of-fit test its important for statisticians to establish an alpha level such as the p-value for the chi-square test. Computing the Chi-Square Test statistic for the Goodness-of-fit Test using MinitabAlternatively for Minitab 19 you can go to Stat - Tables - Chi-Square Go.

Click on Stat choose Tables and then Chisquare Goodness of Fit Test One Variable. Use the goodness-of-fit tests to determine whether the predicted probabilities deviate from the observed probabilities in a way that the binomial distribution does not predict. The p-value is a probability that measures the evidence against the null hypothesis that the data follow the distribution.

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. Use Minitabs Stat Tables Chi-Square Goodness-of-Fit Test One Variable when you have just one variable. Tolerance Intervals Nonnormal Distribution Minitab provides tolerance intervals for the distribution that you choose.

Minitab also has the ability to conduct a chi-square goodness-of-fit test when the hypothesized population proportions are not all equal. If your data follow the chosen distribution you can use the. Interpret a goodness-of-fit test and choose a distribution.

Open the sample data TelevisionDefectsMTW. After you have fit a linear model using regression analysis ANOVA or design of experiments DOE you need to determine how well the model fits the data. The example above tested equal population proportions.

All expected counts are at least 5 so we can conduct a chi-square goodness of fit test. χ 2 O b s e r v e d E x p e c t e d 2 E x p e c t e d. MIL-Hdbk-189 pooled MIL-Hdbk-189 TTT-based Laplace pooled Laplace TTT-based Anderson-Darling.
