    Answer: Independence of Samples

    Explanation:

    ANOVA is the analysis of variance/Assumptions. The Assumptions under ANOVA are:

    The experimental error of data are normally distributed: a mean of the experiments when repeated should be normally distributed.

    There are equal variance between treatments: variances between samples must be evenly spread on each side of the mean.

    Independence of Sample: this assumes that each sample is chosen at random and not dependent on one another.

    Jen's study violates this assumption as her samples are not random.
