A value of <img align="absmiddle" border="0" src="https://www.encyclopediaofmath.org/legacyimages/d/d030/d030400/d0304001.png" /> at which a distribution function <img align="absmiddle" border="0" src="https://www.encyclopediaofmath.org/legacyimages/d/d030/d030400/d0304002.png" /> assumes values equal to <img align="absmiddle" border="0" src="https://www.encyclopediaofmath.org/legacyimages/d/d030/d030400/d0304003.png" /> for <img align="absmiddle" border="0" src="https://www.encyclopediaofmath.org/legacyimages/d/d030/d030400/d0304004.png" />. If deciles exist, they give a fair idea about the shape of the distribution curve. The distance between the ninth and the first decile is called the inter-decile width, which gives an idea of the scatter of the distribution. A decile is a special case of a [[Quantile|quantile]].
