Morphology

interquartile = quartile (transparent) = inter + quartile + quart

Clear prefixation of 'inter-' (between) to the statistical term 'quartile', yielding the adjective meaning 'between quartiles'.

Etymology

Interquartile breaks into inter- meaning 'between' and quartile related to the common word 'quarter', which means 'one fourth'. So, interquartile names the part of a list of numbers that lies 'between' the first and third quarters, and that is why the interquartile range measures the middle spread of data.
