Significance Tests
... • Previously a method was described for comparing two means to test whether they differ significantly. • In analytical work there are often more than two means to be compared. • Some possible situations are: comparing the mean concentration of analyte in solution for samples stored under different c ...

Parametric and Nonparametric: Demystifying the Terms
... assumption is that data are approximately normally distributed. Nonparametric tests do not rely on assumptions about the shape or parameters of the underlying population distribution. If the data deviate strongly from the assumptions of a parametric procedure, using the parametric procedure could le ...

... true, the results from another randomly selected sample will be as extreme or more extreme as the results obtained from the given sample • So the p-value, in some sense, measures how likely our assumption about some property of the population is true • A p-value is always a number between 0 and 1 • ...
