The VIs on this palette can return mathematics error codes. T Test VITests hypotheses about the mean of a population whose distribution is at least approximately normal but whose variance is unknown.Z Test VITests hypotheses about the mean of a population whose distribution is at least approximately normal and whose variance is known.Correlation Test VITests hypotheses about the association between two variables x and y.Sign Test VITests hypotheses about the median of continuous distributions. You must manually select the polymorphic instance to use.Wilcoxon Signed Rank Test VITests hypotheses about the mean of populations whose distributions are continuous and symmetric but not necessarily normal. You must manually select the polymorphic instance to use.Rank Transformation VIFinds the rank order of each element in the x input and returns the order of each element in the rank order x output. For all tied rank values, the mean rank replaces the rank returned.Contingency Table VIComputes the Pearson χ² test for independence. This function is used to test whether the row and column categorical variables of the contingency table are independent.Parent topic: Probability & Statistics
