Take note that there are 10 data values in this data set. It's helpful to sort them in ascending order.
2763,3550,3570,3619,3622,3663,3728,3736,3805,3867
Of these 10 data values, 6 are less than or equal to the data value 3663. To find the percentile rank of 3663, apply the formula:
where L is the number of data values that are less than or equal to 3663, and N is the size of the data set. Substituting in values for this problem, we have:
Substituting
Percentile ranks are always expressed as whole numbers. Evaluating the multiplication above and rounding to the nearest whole number we have:percentile rank = 60
Interpreting our answer, 60% of the numbers in the data set have values less than or equal to 3663.
