A test statistic is a standardized value that is calculated from sample data during a hypothesis test. T-values are an example of what statisticians call test statistics. T-tests are called t-tests because the test results are all based on t-values.

In this post, I will explain t-values, t-distributions, and how t-tests use them to calculate probabilities and assess hypotheses.
#HOW TO USE MINITAB EXPRESS TO FIND T STATISTIC SOFTWARE#
After all, a key reason to use statistical software like Minitab is so you don’t get bogged down in the calculations and can instead focus on understanding your results.

How do t-tests work? How do t-values fit in? In this series of posts, I’ll answer these questions by focusing on concepts and graphs rather than equations and numbers. If you have two groups with paired observations (e.g., before and after measurements), use the paired t-test. You can compare the means of two groups with a two-sample t-test. You can compare a sample mean to a hypothesized or target value using a one-sample t-test. T-tests are handy hypothesis tests in statistics when you want to compare means. Anytime you make this profile active in your Minitab session, you will have access to this toolbar, which you can use to quickly navigate the commands you use most often. Once you have your toolbar built, it will become a part of your active profile. Step 1 may be preliminary graphs, while Step 2 may be analysis and results. This is helpful if you want to organize your toolbar into steps. You can drag this into the toolbar, and then right click and choose to rename it to anything you wish. The picture above illustrates how I accomplished this while building a DMAIC toolbar. In addition to custom toolbars, there is a New Menu command, which can give you even more control over organization. You can add any command you wish that appears in Minitab's menu. You can then drag this command into your toolbar for easy use. This is done by switching to the Commands tab and picking out the commands you want included.įor example, if you wanted a Capability Analysis to be included in your toolbar, you can choose the Stat category on the left and then find the Capability command from the right. From here, we can add menus and commands for different tasks. You can leave it hovering, or you can dock it by dragging it next to an existing toolbar. At this point, a blank box will appear, like this: To add a toolbar, go to Tools> Customize and choose the Toolbars tab. In Minitab, you can do this by creating a custom toolbar to fit your exact needs. While the menus are easy to navigate, you might benefit from grouping all of those commands you use most often in one place. You may have to do a monthly report, for instance, for which you use one tool in our Basic Statistics menu, another in Quality Tools, and a third in Regression.īut there are a lot of functions and capabilities in our software, and if you don't use Minitab every day, it might be hard to remember where specific tools are located. Depending on how often and when you use statistical software like Minitab, there may be specific tools or a group of tools you find yourself using over and over again.
