For example, typing 29 for the Degrees of freedom and 0.95 for the Input constant returns the 95th percentile of the t-distribution with 29 degrees of freedom (1.699), which is the critical value for an upper-tail test with a 5% significance level. Select Inverse cumulative probability, type the Degrees of freedom, select Input constant, and type the lower-tail area (i.e., one minus the one-tail significance level). To find a percentile (critical value) for a t-distribution, select Calc > Probability Distributions > T.Move the qualitative variable into the Indicator variables for box, type a range of columns in which to store the variables (e.g., C5-C6) in the Store results in box, and click OK (check that the correct indicator variables have been added to your spreadsheet in the Worksheet Window). To create indicator (dummy) variables from a qualitative variable, select Calc > Make Indicator Variables.If you get the error message "Completion of computation impossible," this means there is a syntax error in your Expression-a common mistake is to forget the multiplication symbol ( *) between a number and a variable (e.g., 2*'X' represents 2X). Click OK to create the new variable, which will be added to the dataset (check it looks correct in the Worksheet Window) it can now be used just like any other variable. Examples are LOGE('X') for the natural logarithm of X and 'X'**2 for X 2. Current variables in the dataset can be moved into the Expression box, while the keypad and list of functions can be used to create the expression. Type a name (with no spaces) for the new variable in the Store result in variablebox, and type a mathematical expression for the variable in the Expression box. To transform data or compute a new variable, select Calc > Calculator.For example, to find out about "boxplots" click the Index tab, type boxplots in the first box, and select the index entry you want in the second box. You can access help by selecting Help > Help.

Graphs appear in separate windows and can also easily be copied and pasted to other applications. Output appears in the Session Window and can be copied and pasted from Minitab to a word processor like OpenOffice Writer or Microsoft Word.To edit last dialog box, select Edit > Edit Last Dialog or click the Edit Last Dialog tool (ninth button from the left).To open a Mintab data file, select File > Open.If desired, change Mintab's default options by selecting Tools > Options.Getting started and summarizing univariate data

Find instructions for other statistical software packages here. These instructions are based on Minitab 17 for Windows, but they (or something similar) should also work for other versions. The numbered items cross-reference with the "computer help" references in the book. These instructions accompany Applied Regression Modeling by Iain Pardoe, 2nd edition published by Wiley in 2012.
