Manipulating and Calculating Data Overview Manipulating data by hand is time consuming With MINITAB data only needs to be entered once! Then You Can: Rearrange or reorganize data Move or delete rows and columns Convert data from one type to another Control the way data is displayed in data windows and graphs
