The term 'upper or third quartile', also known as Q3, is a concept in statistics that signifies 75% of a particular set of data. This quartile is essentially the median of the upper half of the data, excluding any middle value if present. The process to establish it involves ordering the data from least to greatest, splitting it into four equal segments, and noting the endpoint of the third segment.
