    and it looks like they are listed in order (sorted) for you already so thats a plus. a percentile is a division by 100, we divide it into 100 parts. what position does 63 occupy in the ordered format?

    so, 20 out of 36 = x out of 100 is our comparison

    \[\frac{20}{36}=\frac{x}{100}\] this should give us the percentile of the number 63 in the data set

    56 feels good to me .... not saying its right, but that would be my approach
