MATH201 Software Introduction Minitab Minitab is a very powerful data analysis software package that is also very easy to use. We will be using version 16 in the lab, but version 15 is very similar. You may find Minitab software installed on the PCs in the following computer labs: Morris Library Smith Hall MacDowell Hall Pearson Hall B&E Lab in Purnell Harrington Commons A 30-day free trial version of Minitab may be downloaded at www.e-academy.com/minitab . This site also allows you to rent Minitab for longer periods of time ($30 for 6 months, $50 for 12 months) or buy a copy ($100). Minitab is currently available for Windows only. Excel 2007 While Excel is designed as spreadsheet software, it can perform basic data analysis functions as well. Since Excel is used extensively in business, it’s worthwhile to learn about its statistical capabilities (and limitations). To enable the data analysis features in Excel, you must make sure two add-ins are activated. To do this click on the Office Button in the upper left corner of the window and then select Excel Options . Choose Add-Ins from the menu at the left. You should see the following active application add-ins: Analysis ToolPak Analysis ToolPak – VBA If not, make sure Excel Add-ins are selected to manage at the bottom of the window and click Go . Check the two Analysis ToolPak add-ins and click Ok. You may have to restart Excel for the change to take effect. These two features activate the Data Analysis option under the Data tab at the top of your Excel window. Textbook Datasets You can directly input to Minitab and Excel most of the datasets referenced in your textbook, rather than entering the data by hand. The files are located in the Data folder of the CD that comes with your textbook. The dataset folder has 6 subfolders: Excel, JMP, Minitab14, Minitab15, SPSS, TXT. Each of these has 4 subfolders; the datasets associated with the problems in the problem sets are located in the Exercise folder.
