How to use Minitab t-test? In this post, we’ll look at how to use Minitab to do a one-sample t-test, as well as how to implement and report the given values. For a one-sample t-test to provide the user with a valid result, we have to see many approaches that the data mus...
如果只有两个组,Minitab 将使用 F 检验而不是 Bartlett 检验。 F 检验和 Bartlett 检验仅对于正态分布数据而言才准确。一旦偏离正态性,就会导致这些检验生成不准确的结果。但是,如果数据服从正态分布,则 F 检验和 Bartlett 检验通常比多重比较方法或 Levene 方法更有效。
To run an Anderson-Darling normality test in Minitab, go to Stat > Basic Statistics > Normality Test, pick the columns of data we want to analyze, then Anderson-Darling as the test technique, and press OK. In our product rate example, the p-value is 0.819, indicating that the data fol...
How do F-tests work? Why do we analyzevariancesto testmeans? I’ll use concepts and graphs to answer these questions about F-tests in the context of a one-way ANOVA example. I’ll use the same approach that I use to explainhow t-tests work. If you need a primer on the basics, ...

Explain the basics for performing an inferential test for comparing two proportions. Given below are the analysis of variance results from a Minitab display. Assume that you want to use a 0.05 significance level in testing the null hypothesis that the different samples come from populations ...
How is SPSS used to perform the calculations needed for a one-tailed or two-tailed test? SPSS: SPSS is used for the visualization of the enormous range of data values. It helps an experimenter with the complex and large data by giving the quick descriptive in ta...
I’m using Minitab, which can test 14 probability distributions and two transformations all at once. Let’s take a look at the output below. We’re looking for higher p-values in the Goodness-of-Fit Test table below. As we expected, the Normal distribution does not fit the data. The ...
