6. Explain the Data Types in Minitab?
Minitab will recognize Text, Numeric, and date/time; when we enter data into any column, Minitab automatically assigns a data type to that column based on the first value entered, and all the data entered in a column should have the same data type. We can change the data types in Minitab.
- Numerical: For Statistical Calculations, numerical data is the only type in Minitab. Numerical data is associated with the right side of the column. Minitab will not recognize numbers with commas; instead, they will be considered as text.
For example C1
- Text: For computation purpose, ‘Text’ can’t be used. If any column contains text in it, that column name/label will be changed from CI to CI-T.
For example C5-T
- Date/Time: Minitab recognizes Date and Time Data Types, but it stores them internally as a number to manipulate them in the future if the requirement comes. If we put the D label after the column name, then it will indicate the date or time column type.
For example C1-D
7. What are the symptoms of corrupted projects in Minitab, and how to recover them?

- Error messages come out when we try to open the project or update any graph.
- Some items will miss from the project after we save and reopen the project.
- Sometimes a project does not seem to open, and graphs that appear to be linked to the worksheet are not really linked.
Below is the list of items to recover the corrupted projects in Minitab
- Try to retrieve the backup file of the project – When we open a project file, Minitab automatically creates and saves a backup file in the same project folder with a specific file format. For example, is the project file is PROC.mpj, then the backup file would be PROC.mpj.BAK.
- Try recovering individual worksheets – if we cannot retrieve the backup copy, we can try recovering individual worksheets.
- Raising a support ticket with Minitab– we can send the project files to the Minitab team, copy the project and the BAK file and send those to firstname.lastname@example.org; they might help us in resolving the issue.
