UNCLASSIFIED / FOUO Learning Objectives Become familiar with the Minitab statistical software Learn some of the most widely used tools within Minitab Learn how to navigate within Minitab UNCLASSIFIED / FOUO 3 4. UNCLASSIFIED / FOUO Overview FEAR NOT!Minitab is a good tool for beginners, as well as established statisticiansThis is just an introduction Minitab is a powerful tool that is capable of much more than what we will have time to cover hereSuggestion: For now, do not be concerned with all the bells and whistlesMinitab Help function is always available and easy to useUNCLASSIFIED / FOUO 4 5. UNCLASSIFIED / FOUO What Will We Cover? We are going to cover just a few of Minitab tools, including:The Minitab layoutAn overview of the menusThe Minitab CalculatorSome BASIC statistical toolsSome BASIC graphing toolsThe HELP menu UNCLASSIFIED / FOUO 5 6. UNCLASSIFIED / FOUO Minitab Layout The overall lay out of Minitab is similar to Excel, with some key differences:The worksheet looks similar to a spreadsheet, but Minitab prefers data to be in columns. An easy way to think of it is to think of each column as a variable: Time, speed, date, etc.The Session Window is a dialog window. It is where the non-graphical results of your calculations will be displayed. UNCLASSIFIED / FOUO 6 7. UNCLASSIFIED / FOUOWhat Does It Look Like?Session WindowWorksheet UNCLASSIFIED / FOUO 7 8. UNCLASSIFIED / FOUO Minitab Characteristics Although not a Microsoft product, Minitab shares some characteristics of other programs running on the Windows platform. In particular, the menu bar running across the top of the page, and the button bar below that. We will briefly go through some of the key functionality in the menu bar. The button bar contains shortcuts to many of the same functions. Also, you can cut and paste data from Excel. You can do this by simply using the Ctrl-C and Ctrl-V functions you might already be familiar with. UNCLASSIFIED / FOUO 8 9. UNCLASSIFIED / FOUO Minitab Characteristics One of the key differences in Minitab is the distinction between a Project and a Worksheet Worksheets contain your data and nothing else. It is where you can manipulate the data and store your data. Minitab will let you have several worksheets open simultaneously. In addition, worksheets can be saved independently and shared between projects. Projects are more like an entire notebook, containing not only one or more worksheets, but also your session window (containing any analysis you have already performed) and any graphs you have createdUNCLASSIFIED / FOUO 9 10. UNCLASSIFIED / FOUOFile Menu Select File ProjectCommandsWorksheetCommandsRecentlyOpened Worksheets UNCLASSIFIED / FOUO 10 11. UNCLASSIFIED / FOUOEdit MenuSelect Edit The most frequently used featurefound under the Edit drop downmenu is the Edit Last Dialogwhich can (and should) be quicklyaccessed by using the Control-Equick key combination.This feature will allow you toquickly access the last dialog boxyou used and either re-run,change, or review the last analysis Select you performed.Edit Last Dialog UNCLASSIFIED / FOUO 11 12. UNCLASSIFIED / FOUOData Menu Select DataThe Data menu contains severalColumn manipulation features.Two examples are the Column Select Stack and Unstack features.Unstack ColumnsThese features allow you toor Stack Columnscombine multiple columns (orrows) into one, or break onecolumn (or row) into multiplecolumns (or rows).UNCLASSIFIED / FOUO 12 13. UNCLASSIFIED / FOUO Pizza Example Lets work through an example of this. Open theMinitab worksheet called Pizza Exercise.mtw. We are going to stack the columns with the differentdefect types so that we can make a Pareto chart UNCLASSIFIED / FOUO 13 14. UNCLASSIFIED / FOUOPizza Example (Cont.) Step One: Open data setPizza Exercise.mtwUNCLASSIFIED / FOUO 14 15. UNCLASSIFIED / FOUO Pizza Example (Cont.) First, lets add a couple of headers for the columns we are about to stack The first column we will call Defect Type and it will be where the defect types will be listed. We will put that header over column C11. The other column we will call Count and that is where we will put the count for each defect type. We will place that over column C12.UNCLASSIFIED / FOUO 15 16. UNCLASSIFIED / FOUOPizza Example (Cont.)Step 2: Type in the two new column headersC11 = Defect TypeC12 = CountUNCLASSIFIED / FOUO 16 17. UNCLASSIFIED / FOUO Pizza Example (Cont.) Now, lets go to the Data menu: Data>Stack>ColumnsUNCLASSIFIED / FOUO 17 18. UNCLASSIFIED / FOUOPizza Example (Cont.) Data> Stack>Columns Step 3: Select Data,choose Stack and finally, select ColumnsUNCLASSIFIED / FOUO 18 19. UNCLASSIFIED / FOUO Pizza Example (Cont.) We are going to stack all the columns that list the different defect types. That would include Late, Wrong Ingredients, Wrong Order, Wrong Address, and Damaged. Highlight all these columns and select them for the Stack the following columns box. We have a few choices for where to put the new stacked columns. Remember we created two headers for the new columns: Defect Type and Count. Since these columns are on the current worksheet, we select the radio button labeled Column of current worksheet. This will open up two more fields for us to place the stacked columns. In the first field, next to Column of current worksheet, select the Count column. Next, in the field labeled Store subscripts in, select the Defect Type column. Make sure that the box labeled Use variable names in subscript column is selected. Remember, Minitab often refers to columns as variables. When done, click OK UNCLASSIFIED / FOUO 19 20. UNCLASSIFIED / FOUOPizza Example (Cont.) Data>Stack ColumnsStep 4 Highlight thecolumns you wantstacked, then click Select to cause them to appear here Step 5 We want the datastored in the currentworksheet, so selectthis Radio Button,enter data andclick on OKUNCLASSIFIED / FOUO 20 21. UNCLASSIFIED / FOUO Pizza Example (Cont.) There you go! We will come back to this worksheet a little later and use these stacked columns to create a Pareto chart UNCLASSIFIED / FOUO 21 22.

UNCLASSIFIED / FOUO Calc Menu The Calc menu contains a wealth of tools that you will be using on a regular basis. We will touch on them only briefly here. Twosuch items are the Column Statistics and Row Statistics features. These items allow you to run simple calculations such as the sum, mean, median, and standard deviation on a row or column of data. The result will be displayed in the session window. Two other commonly used items are the Make Patterned Data, and Random Data functions Make Patterned Data will allow creating series, such as 1,2,3,1,2,3 etc. This is good for coding items such as days of the week. RandomData can do a couple of things for you. Not only can you create a set of random numbers, but this function can also be used to randomize a column of data.UNCLASSIFIED / FOUO 23 24. UNCLASSIFIED / FOUOCalc Menu (Cont.) Select CalcTo Get The Following Drop-Down Menu UNCLASSIFIED / FOUO 24 25. UNCLASSIFIED / FOUO Calc Menu (Cont.) The Calculator is a very commonly used tool. The power behind the calculator is that it allows us to perform a wide range of mathematical and statistical functions not only on a column of data, but between columns of data.UNCLASSIFIED / FOUO 25 26. UNCLASSIFIED / FOUOThe Calculator The Calculator Dialog BoxUNCLASSIFIED / FOUO 26 27. UNCLASSIFIED / FOUO The Calculator Example Lets Look at an Example: AnthonysPizza delivery company was interested incustomer service problems with pizzas that theydelivered. Over a 12-day period, they recorded howmany pizzas they delivered, and how many had defectsthat fell into the following categories: Late, WrongIngredients, Wrong Order, Wrong Address, andDamaged. In addition, they recorded the Pizza Stylistwho was making the pizzas each day. Whenthey were done collecting the data, they keyed itinto the Minitab worksheet in Columns C4 thru C9.UNCLASSIFIED / FOUO 27 28. UNCLASSIFIED / FOUO The Calculator Example (Cont.) For this example, lets say that we want to know how many total defects we had each day. Since we know how many of each type of defect we have, all we need to do is add all of the defect columns together. We will use the Calculator to calculate this result, and put the result in column C10 Lets start by typing the header for column C10 and calling it Total DefectsUNCLASSIFIED / FOUO 28 29. UNCLASSIFIED / FOUOThe Calculator Example (Cont.) Type in the newcolumn header forTotal Defectsin column C-10 UNCLASSIFIED / FOUO 29 30. UNCLASSIFIED / FOUO The Calculator Example (Cont.) Nowwe can have some fun! Wewant to store the result in
