There are three datatypes in Minitab:
The Numerical data is aligned to the right side of the column. This is essentially used for statistical calculations
The text cannot be used for computations or calculations. If column 1 has text in it, the label of the column will be changed to CIT.
Minitab Recognizes 3/5/00 as date and 5:30 as a time but the date and time are internally stored as numbers. The column label can be identified as date and time by mentioning D after the column name. Minitab can change Datatypes.
Minitab can do the following transformations:
Numeric to text
Text to numeric
Date/Time to text
Date/Time to numeric
Numeric to Date/Time
Text to Date/Time
