How do you work out a percentile rank of a score of 57
arlik [135]
To do that you'll need the mean and standard deviation of all the scores.  Can you provide this info?

For example:  Supposing that the mean of these scores were 52 and the standard deviation 3.  You'd need to find the "z-score" of 57 in this case.
               57 - 52
It is  z = ------------ , or z = 5/3, or z = 1.67.
                     3

Find the area to the left of z = 1.67.  Multiply that area by 100% to find the percentile rank of the score 57.

From there on we simply do addition.

1+1+1.25+1.5+1.5=6.25
