ANOVA: One-Way

How to perform a One-way ANOVA in jamovi:
  1. You need one continuous dependent variable, and one nominal grouping variable with two or more levels.
    A correct setup should look similar to this:

    data_format_unianova


  2. Select Analyses → ANOVA → One-way ANOVA.

    select_unianova


  3. Drag and drop your outcome variable to Dependent Variable and your grouping variable to Fixed Factors.

    add_var_unianova_1


  4. Select whether your variances are equal or unequal. To test for equality of variancess using Levene’s test, tick the box Equality of variances.

    add_var_unianova_2


  5. The results are shown in the right panel:

    output_unianova
