Percentiles - A number that corresponds
to one of 100 equal divisions in a range of

value such that at least p% of the items in
the data set are less then or equal to its
value and at least (100 - p)% of the items
are greater than or equal to it; example:
the 60th percentile means that 60% of
values in the data set are less than or equal
to it and (100 - 60) 40% are greater than or
equal to it.
Percentage of the median - A fraction or
ratio based on a total of 100, where the
median value of the data set equals 100; a
value that equals a proportion or part of a
