One-way ANOVA

Computes statistics for the one-way analysis of variance (ANOVA). It is designed to compare the means of observations in the same column between several groups. The node allows the testing of equality of variances (Levene's test) and provides the relevant descriptive statistics.

Options

Factor: Column holding the grouping information data.
Confidence Interval (in %): The limits for the confidence interval are computed using this number. The default is 95 which means that you can be 95% confident that the true value of the parameter is in the confidence interval.
Test columns: A one-way ANOVA is performed separately for each of these columns.
