This calculator estimates the prediction limits for your data. These are used to test if a model is predicting well.
Standard Deviation can either be the Standard Deviation for several repeated runs or a pooled Standard Deviation or "Pure Error" from a designed experiment.
Degrees of Freedom is N-1 for repeated runs. If you are using Pure Error, look up the degrees of freedom your software reports.
