    One way ANOVA test assumes that

    The dependent variable is continuous, and the independent variable is categorical;

    Independent Observations- Random and independent experiment design, for example, we can not have the same person be tested on three instructions (dependent design);

    Samples are normally distributed and have similar standard deviation (when there is a 3 group sample σ1 = σ2 =σ3)- Normal distributed error terms & equal error variances
