1 Minitab® 15 Tips and Tricks
-Use the Weld Strength.xls and Production.mdb files.

2 Importing and Manipulating Data
Worksheets Graphics Customizing Minitab Additional Tips

3 Importing Excel Files In Minitab, choose File > Open Worksheet

4 Importing Excel Files In the File > Open Worksheet dialog, use Options and Preview before opening file

5 Importing Excel Files Correctly-formatted sheets open into separate worksheets

6 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

7 Importing Data from a Database
Select the tables and fields that you want to import Select Use rows… to specify a condition statement Production.mdb – A productivity improvement team tracks equipment downtime for two manufacturing lines. For each manufacturing line, daily production sheets track downtime information. At the end of each day, the manufacturing clerk enter info about each downtime occurrence into a Microsoft Access database. [Use this data until slide 22.] If you get a account/user name error, choose Start > Control Panel > Admin Tools > Data Sources (ODBC) > select MS Access Database > Configure > under System Database, select None > OK > OK.

8 Tally Individual Variables
Use Stat > Tables > Tally Individual Variables to get a list of unique values for a given column Tally will help you easily identify any inconsistencies Using the imported data from Production.mdb…

9 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: Use Alt to highlight the column of values > Copy Paste the column into the worksheet Create a column of the new, coded values Data > Code > Use Conversion Table Input Column: Reason Output Column: Reason Conversion Table Column of Original Values: c8 Column of New Values: c9

10 After Data are Coded Now we can create Pareto charts, get Descriptive Statistics, etc. for the downtime reasons

11 Split and Subset Worksheet
Use Data > Split Worksheet to create new worksheets for each unique value in a column Use Data > Subset Worksheet to create a new worksheet based on a condition, brushed rows or specific row numbers

12 Value Order Value order determines the ordering of variables
Right-click on a column and choose Column > Value Order to define an order Speeds displayed in Alphabetical Order (default) Speeds now displayed in a User-Specified Order

13 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

14 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

15 Importing and Manipulating Data
Worksheets Graphics Customizing Minitab Additional Tips

16 Formulas in the Worksheet
Use Calc > Calculator to assign formulas to columns in the worksheet Columns update when data in the worksheet change

17 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

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

19 Multiple Undo and Redo Use the arrows on the toolbar to undo or redo changes made to cells in the worksheet undo redo

20 Autofill Use autofill to create patterned data
Use the Control key to create repeated patterned data

21 Importing and Manipulating Data
Worksheets Graphics Customizing Minitab Additional Tips

22 Split Graph into Panels
Right-click on a cluttered graph and choose Panel to reduce the clutter Before paneling After paneling

23 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

24 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

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

26 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

27 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

28 Graph Editing Toolbar examples
Use the Add List dropdown to add gridlines, reference lines, subtitles and data labels Use Crosshair mode to explore graphs

29 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. Before Editing After Editing

30 Make Similar Graph Use Editor > Make Similar Graph to create a similar graph using different variable(s)

31 Layout Tool To combine multiple graphs into one window, choose Editor > Layout Tool

32 Updating Graphs Available for core graphs and Control Charts
Right-click on icon in upper left corner to update graph Automatic Updates – sets graph to automatically update anytime data in worksheet change Update Graph – performs one-time update Core Graphs and Control Charts All Other Graphs Graph is up-to-date Graph is up-to-date, but cannot be updated “Core graphs” corresponds to any graphs created using the Graph menu. Note: If you move columns, a core graph or control chart’s icon can turn to a white ‘X’. Data used to create graph have changed Data used to create graph have changed, and graph cannot be updated On-hold, some condition prevents auto-update

34 Tools > Options Use Tools > Options to set default preferences
For example, specify a default file location that Minitab will go to when using File > Open Project

35 Tools > Options > My Footnote
To easily keep track of which worksheet was used to create each graph, set a footnote to automatically display the worksheet name

36 Tools > Options > Descriptive Statistics
Select the statistics you need when using Stat > Basic Statistics > Display Descriptive Statistics
