Upper Quartile Definition and Formula. The upper quartile is the median of the upper half of a data set. This is located by dividing the data set with the median and then dividing the upper half that remains with the median again, this median of the upper half being the upper quartile.
One definition refers to the subset of all data values in each of those parts. For example, if I say my score was in the upper quartile on that math test, I mean that my score was one of the values in the upper quartile subset (i.e. the top 25% of all scores on that test). But the terms can also refer to cut-off values between the subsets.
