GraphPad Quick Calcs

  • Product Description: We have created dozens of free online calculators for radioactivity calculations, detecting outliers, t tests, randomizing, and much more. QuickCalcs are free and there is nothing to install, so check them out. A few of the QuickCalc calculators do analyses in Prism and InStat (i.e. t test, chi-square) but most of the calculators do not duplicate functions in Prism and InStat, and none duplicate the capability of StatMate
