Log onto the PC and select Start > Programs > Minitab 15 for Windows > Minitab to run MINITAB Release 15. 2. The Minitab window will appear. Within it are two smaller windows – the top one is called the Session window and the bottom one is called the Data window. 3. To get Minitab to execute commands, such as calculating the sample mean or plotting some data, you can use the pull down menus. It is also possible to type commands in the Session window. 4. The Data window displays the data set you’re currently using. Minitab calls this the current worksheet.
