Specify settings for calculating formulas when you change the associated data or save a project or worksheet. Minitab uses the options you set here each time you assign a formula to a column in the worksheet. The changes you make to the defaults remain until you change them again, even after you exit Minitab.
Calculation
Automatic: Calculate formulas automatically every time the associated data change.
Manual: Calculate formulas manually.
Calculate Before Saving Project or Worksheet
Always calculate the formulas: Minitab automatically calculates the formulas when you save a project or worksheet.
Never calculate the formulas: Minitab doesn't calculate the formulas.
Ask whether or not to calculate the formulas: Minitab asks you whether to calculate the formulas when you save a project or worksheet.
