The first quartile is a quarter of the way through. For example in a list of 700 numbers the third quartile has an index of 075 700 525 which we add 05 to and get 5255. First quartile is the value below which 25 one-fourth of the cases fall. The third quartile or upper quartile is the value that cuts off the first 75.
