For the given set of data and score, the calculator will find the percentile class rank, with steps shown.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please write it in the comments below.

Your Input

Find the percentile rank of $$$2$$$ in $$$2$$$, $$$3$$$, $$$-5$$$, $$$7$$$, $$$1$$$, $$$5$$$, $$$5$$$, $$$2$$$, $$$8$$$, $$$4$$$, $$$2$$$, $$$-5$$$, $$$-3$$$, $$$7$$$.

Solution

The number of values is $$$N = 14$$$.

The number of values less than the score is $$$L = 4$$$.

The number of values equal to the the score is $$$S = 3$$$.

Thus, the percentile rank is $$$PR = \frac{L + \frac{S}{2}}{N}\cdot 100\% = \frac{4 + \frac{3}{2}}{14}\cdot 100\% = \frac{275}{7}\%$$$.

Answer

The percentile rank of $$$2$$$A is $$$\frac{275}{7}\%\approx 39.2857142857143\%$$$A.
