Plus l’intervalle interquartile est grand, plus la dispersion est forte. Plus l’intervalle est petit, plus la série est « concentrée » (rassemblée) autour de la moyenne. Un des inconvénients de l’intervalle interquartile comme de l’intervalle inter-décile apparaît quand il s’agit de faire des comparaisons. L’intervalle interquartile s’exprime dans la même unité que celle de la variable. Il est donc difficile de comparer des distributions qui sont exprimées dans des unités différentes. Les quartiles constituent avec les déciles, un des types de « quantiles » les plus utilisés.
