Oneway Analysis

Examine Relationships between a Continuous Y and a Categorical X Variable

Using the Oneway or Fit Y by X platform, you can explore how the distribution of a continuous Y variable differs across groups defined by a single categorical X variable. For example, you might want to find out how different categories of the same type of drug (X) affect patient pain levels on a numbered scale (Y).

The Oneway platform is the continuous by nominal or ordinal personality of the Fit Y by X platform. The analysis results appear in a plot, and you can interactively add additional analyses, such as the following:

a one-way analysis of variance to fit means and to test that they are equal

nonparametric tests

a test for homogeneity of variance

multiple-comparison tests on means, with means comparison circles

outlier box plots overlaid on each group

power details for the one-way layout
