Below is the list of Data Analysis functions in Minitab
•Correlation, ANOVA, Tests on Proportions, Variance Tests, Sample Size and Simple Linear Regression and Sample t-Test.
5. 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 on the right side of the column. Numbers with commas will not be recognized by Minitab instead it 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 so that we can manipulate them in future if the requirement comes. If we put D label after the column name, then it will indicate the data or time column type.
For example C1-D

- 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 are not able to 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 email@example.com, they might help us in resolving the issue.
