Data Window
The second horizontal row just below the column labels C1, C2, … is reserved for variable names. White
spaces and special characters such as &, # . are not allowed for variable names. Data window is very similar to
a spreadsheet. You may use arrow keys or mouse pointer to move around the data sheet.
Once the data set is entered you can use the menu bar items to manipulate data. Most menu commands give you
a dialog box to select variables, and/or input other constants required for the procedure. You have to select the
variables you want by double clicking on them. The output will appear on the session window and can be
printed or copied into another word processor. When you copy a graph use paste special to paste to your
document to avoid any device dependency. When submitting Minitab assignments you should type your name
and question number at the top of the work sheet. You can get a new line by moving to the top of the session
window and pressing enter button. No photocopies are allowed.
Following is a partial list of data obtained from a survey of 146 students.
