To find Percentile rank of X =6.5:

4,4,4,5,5,6,6,6,6,7,8,8,9,9,10,11

Total number of observations = 16

Percentile rank formula:

$\text{percentie rank}=(\frac{L}{N})(100)$

Of these 16 data values, 9 are less than or equal to the data value 6.5

$\text{percentie rank}=(\frac{9}{16})(100)\phantom{\rule{0ex}{0ex}}\text{percentie rank}=(0.5625)(100)\phantom{\rule{0ex}{0ex}}\text{percentie rank}=56$

Therefore, the percentile rank of X =6.5 is 56%
