Default Calculating Percentiles of Test Scores?

IGNORE MY PREVIOUS POST:


Percentile is related to position in the list rather than relative score.
In B1 use:
=(COUNT(A:A)-ROW())/COUNT(A:A)*100

Percentile should represent the percent of the population with scores lower
than the given score.

Normalize the scores to the maximum (not perfect) sco


Say you have 75 scores in column A sorted from highest at the top to lowest.
In B1 enter:

=A1/$A$1 and copy down thru B75. Format column B as percentage.
or
=100*A1/$A$1 and copy down thru B75. Format column B as number fixed places 0


If you had thousands of scores you would bin them. For example, all scores
between 74.5% and 75.5% would be in the 75th percentile.

I have a list of 75 test scores, and I have to calculate the percentile
of each test score and what percentile corresponds to what score.
Anybody have any ideas to make this easier? I already put all the test
scores in order.
