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 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 $$$\frac{275}{7}\%\approx 39.285714285714286\%$$$A.
