INTRODUCTION TO MINITAB Minitab is a popular statistics software package which is able to describe, analyze, and display data. When you use Minitab, it creates a worksheet where your data will be stored. Minitab works in several windows at once, although not all of the windows may be visible to you at any one time. Windows that are not visible may be accessed by selecting Windows from the menu bar. The windows you will be using most often are described below. THE DATA WINDOW The Data Window looks like a spreadsheet and contains data arranged in columns (C1, C2, C3, etc.) and rows (1, 2, 3, . ..). Usually, the columns will represent the variables you are using. The intersection of a row and a column is called a cell ; the cells are where you will enter and edit your data.

ENTERING DATA FROM THE KEYBOARD Click on the Data window to activate it. The cell that is highlighted is the current or active cell, and data you type in will be entered into this cell. You can activate any cell by clicking on it. Type in your data one cell at a time; if you make a mistake, use [Backspace] to delete a character. Pressing [Enter] will enter your data and move you one cell down ; pressing [Tab] will enter your data and move you one cell to the right. You can also use the arrow keys to move around the worksheet. NAMING COLUMNS It is easier to work with data if you assign a meaningful name to each column in your worksheet. Column names are entered in the name row below the column labels. Column names cannot: - be longer than 31 characters - begin or end with a blank - include the symbol ` or # - start with or consist entirely of the symbol * - be repeated; you cannot use the same name for two columns in a worksheet OPENING AN EXISTING WORKSHEET Choose File Open Worksheet A dialog box will appear. Choose the disk drive and folder where the worksheet is stored. Choose the type of file you need, which is Minitab (*.mtw; *.mpj) Find the file you want in the Files list box, and then double-click on the filename, or highlight the filename and click on [OK] or press [Enter] You will then see the data entered in your worksheet.

Page 3 THE SESSION WINDOW The Session Window keeps a record of all of the commands you give Minitab and will also display the results of many of those commands. The commands may be typed in at the Minitab prompt (MTB> ) or may be entered using the Minitab menu that you see at the top of the window. Note: If you do not see the Minitab prompt MTB> in your Session Window, select Editor Enable Commands from the Minitab menu. Be sure the Session Window is active. GETTING HELP In addition to the pull-down Help menu, you can get help on any command by clicking on [Help] on the lower left corner of the dialog box, or on the question mark symbol in the toolbar.
