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.
Lower extreme: the lowest or smallest value in a set of data. Lower quartile or first quartile: the median of all data below the median. Median or second quartile: the middle value of the set of data. If there are two values in the middle, the median is the average of the two values. Upper quartile or third quartile: the median of all data above the median. Upper extreme: The biggest value in the set. Example: Construct a box and whiskers plot for the data set: {5, 2, 16, 9, 13, 7, 10}. First, you have to put the data set in order from greatest to least or from least to greatest.
