    Pearson's coefficient of skewness =

    If the mode is to the right, then you have a negative coefficient.

    In your diagram, the mode is directly over the mean, meaning that mode = mean... so, the Pearson's Coefficient is ?

    The Pearson's Coefficient is 0 ?

    Yes, I would think that it's correct.

    I didn't do that at school, but since my book also has regression... :)
