Specify the default settings for calculating formulas when the data change

File > Options > Formulas

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.
