INTRODUCTION TO MINITABMinitabis 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 windowsat 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 ►Windowsfrom the menu bar. The windows you will be using most often are described below. THE DATA WINDOWThe Data Windowlooks 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.
