    Assuming Equal Variances- what to do?




    Hello,

    On my data I have assessed whether it's parametric. The distribution is normal, however on the Levene Statistic test, it has a significance level of 0.130- which means I have to assume equal variances.

    What are the next steps to take from this?
    Should I just use a non-parametric test? (Kriskal-Wallis test)
    Or should I carry on with a one-way anova (and if so, what other implications must I consider)

    Any help will be greatly appreciated!

    Data isn't parametric. Some data can be modeled by certain distributions but data is just data.

    You don't have to do anything. The p-value doesn't give conclusive evidence that there seems to be a difference in variances though. This is a good thing - life is easier when we can assume equal variances which is why what you say later puzzles me. It sounds like you think that it's a bad thing that you can assume equal variances? What gave you that impression?
    I don't have emotions and sometimes that makes me very sad.
