Minitab Quick Reference

Every classroom activity has instructions on the website with the details of using Minitab for that activity. This is a quick guide to the commands we'll use and they unit where they'll be introduced.

Each screen in Minitab has a help button you can click for additional help. This document is intended to get you to the right place in Minitab, not be a comprehensive guide of how to use it.

Unit 1: The Basics

Stat » Basic Statistics » Display Descriptive Statistics

Used to summarize numerical data, find the mean, standard deviation, variance, etc. The by variables is an optional variable used to group the data. Use the statistics button to change what values are displayed. In particular, we will often turn on the variance.


Almost all of the graphs except for the graphical summary are found here.

Numerical Data

Categorical Data

Stat » Basic Statistics » Graphical Summary

This is a graph with multiple plots that show a lot of the information about a numerical variable. It includes a numerical summary, histogram, confidence interval, and test for normality.

Calc » Calculator

Used to transform the data or generate new variables.

Unit 2: Probability

Calc » Make Patterned Data » Simple Set of Numbers

Create a list of numbers without having to type them all in.

Calc » Make Patterned Data » Text

Create a sequence using text. Separate your words with spaces. If there are spaces within your phrases, enclose them in quotes (Alien "American Pie" Jaws).

Calc » Random Data » Sample from columns

Useful for simulation purposes and sampling.

Calc » Probability Distributions » Binomial

Find binomial probabilities. The cumulative probability is the area to the left of the value and the probability is the chance of getting that value.

Graph » Probability Distribution Plot

Used to graph a distribution.

Calc » Probability Distributions » Normal

Find normal probabilities. This is easier done with the online probability calculator, but Minitab does allow you to specify a different mean and standard deviation.

Unit 3: Inferential Statistics

Stat » Basic Statistics

Almost everything we do in this unit is a choice under basic statistics.

Numerical Data

Categorical Data

Graph » Probability Distribution Plot

Used to graph a distribution. Choose view probability when creating hypothesis testing graphs.

Graph » Probability Plot

Don't confuse this with the probability distribution plot. This is used to see whether a group of data has a particular distribution. We are usually checking for normality. The data has the distribution you're testing for if the points basically fall along the line with no systematic patterns or outliers.

Unit 4: Advanced Topics

Stat » Tables » Chi-Square Goodness-of-Fit Test (one variable)

Use this to perform the chi-square goodness of fit test.

Stat » Tables » Cross Tabulation and Chi-Square

Use this to perform a test for independence. Click the chi-square button and select the chi-square analysis.

Stat » ANOVA » One Way

Use this to perform a one-way ANOVA test. There should be two columns, one for the factor (grouping) variable and one for the response (numerical) variable. If you created a variable for each group, then use the unstacked test.

Stat » ANOVA » Two Way

Use this to perform a two-way ANOVA test. There should be three columns, two grouping variables for the row and column factors and one for the response (numerical) variable.

Graph » Scatterplot

Used to graph two paired numerical variables.

Stat » Basic Statistics » Correlation

Used to perform correlation between two or more variables.

Stat » Regression » Regression

Used to perform both simple and multiple linear regression.
