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.
1 The Upper Quartile Q3 is that number such that 75% of observations are less than it and 25% are larger, or to be more precise, at least 75% of the sorted values are less than or equal to Q 3, and at least 25% of the values are greater than or equal to Q 3.ote that the numbers 1, 2 are less than or equal to the lower quartile, while 2, 3, 4, 5, 6, 7 are larger than or equal to Q 1. Therefore, 2 out of 7 or 28% of values are less than or equal to Q 1 and 6 out of 7 = 85% are larger than Q 1.
