how many data points are there?
OpenStudy (theislander):
36
OpenStudy (amistre64):
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?
OpenStudy (theislander):
20

im looking at the 36 arent i
OpenStudy (amistre64):
63 is the 20th number .. youre right
OpenStudy (amistre64):
so, 20 out of 36 = x out of 100 is our comparison
OpenStudy (amistre64):
\[\frac{20}{36}=\frac{x}{100}\]
this should give us the percentile of the number 63 in the data set
OpenStudy (theislander):
x=55.6
