Parametric Methods

 

Menu location: Analysis_Parametric

• Paired t test (compare a pair of samples)
• Single sample t test (compare the mean of a sample with a specified mean)
• Unpaired (two sample) t test (compare two independent samples)
• Z (Normal distribution) tests (single sample and unpaired tests analogous to t tests)
• Reference range (reference range/interval from a sample)
• F (variance ratio) test (compare the variances of two samples)
• Poisson confidence interval (e.g. CIs for means of counts of events in time)
• Normality tests (examine a sample for evidence of non-normality)

 

This section provides various hypothesis tests and descriptive functions that assume your data are from a normal distribution.
