Minitab® 15 Tips and Tricks


Importing and Manipulating DataWorksheetsGraphicsCustomizing MinitabAdditional Tips


Importing Excel Files

In Minitab, choose File > Open Worksheet



In the File > Open Worksheet dialog, use Options and Preview before opening file



Correctly-formatted sheets open into separate worksheets


Importing Data from a Database

In Minitab, choose File > Query Database (ODBC), select Machine Data Source and then your database

Note: Use File > New > Minitab Worksheet to import data into a blank worksheet


Importing Data from a Database

Select the tables and fields that you want to import

Select Use rows… to specify a condition statement


Tally Individual Variables

Use Stat > Tables > Tally Individual Variables to get a list of unique values for a given columnTally will help you easily identify any inconsistencies


Coding and Conversion Tables

Use Data > Code > Text to Text if you need to code up to 8 values

Use Data > Code > Conversion Table to code any number of text or numeric values

To create a conversion table:1. Use Alt to highlight the

column of values > Copy

2. Paste the column into the worksheet

3. Create a column of the new, coded values


After Data are Coded

Now we can create Pareto charts, get Descriptive Statistics, etc. for the downtime reasons

Extract from Date/Time

Suppose we want to evaluate the variation across the different days of the week

Use Data > Extract from Date/Time to record date or time components in a numeric or text column


Change Data Type

Suppose you import data and find that a numeric column is incorrectly formatted as text

Use Data > Change Data Type > Text to Numeric to change the column format


Formulas in the Worksheet

Use Calc > Calculator to assign formulas to columns in the worksheet

Columns update when data in the worksheet change


Worksheet and Column Descriptions

Right-click on a column and choose Column > Description to add notes for future reference

Right-click on to add a Worksheet Description


Worksheet Zooming

Use the Control key and your mouse wheel to zoom in and out of the worksheet


Multiple Undo and Redo

Use the arrows on the toolbar to undo or redo changes made to cells in the worksheet

undo redo


Autofill

Use autofill to create patterned data

Use the Control key to create repeated patterned data

Brushing Options

We see strength values that are lower than expected and want to do further investigation

Right-click > Brush > right-click > Set ID Variables


Brushing Options

Brush multiple groups of points using the Shift key

The brushing window shows that all lower weld strengths are associated with the third shift


Brushing Options

The Data Options button for any Graph or Control Chart allows you to include or exclude data based on brushed rows


Graph Annotation Tools Toolbar

Choose Tools > Toolbars to enable the Graph Annotation Tools toolbar

The Graph Annotation Tools toolbar is useful for adding text, circles, and arrows to graphs

Select Mode Rectangle Line Polyline

Text Ellipse Marker Polygon


Graph Editing Toolbar

Choose Tools > Toolbars to enable the Graph Editing toolbar

The Graph Editing toolbar is useful for editing graphs and obtaining graph coordinates

Select List Select Crosshair Add List Zoom

Edit Brush Plant Flag Delete


Graph Editing Toolbar examples

Use the Add List dropdown to add gridlines, reference lines, subtitles and data labels

Use Crosshair mode to explore graphs


In-Place Graph Editing

Double-click on the graph components to change fonts, colors, add a date/time stamp, etc.

Right-click on the graph to add titles, gridlines, data labels, etc.

Exec macros

If you need to conduct the same analysis on a regular basis, consider creating an Exec, a type of macro, to easily re-run the same analysis

Click to go to the History window and highlight the desired commands


To save an Exec

To save the commands as an Exec, right-click on the highlighted History commands and choose Save As…

Save the *.MTB file to your hard-drive


To run an Exec

Run the Exec at any time using File > Other Files > Run an Exec > Select File and browse to your *.MTB


Tools > Customize

Use Tools > Customize to:• Move, add, edit, or delete any item on a toolbar or

menu• Create a new toolbar or menu• Set custom keystrokes for frequently used

commands• Add a button to call your Exec file
