Mahalanobis used a visual method of approximating the standard error of the income at all the fractiles of the covariate for the same graph by taking two independently selected "interpenetrating subsamples" and obtaining a graph for each of the subsamples besides the combined sample. […] The method proposed by Mahalanobis for estimating the error area of a fractile graph was later hailed as a precursor to the genesis of latter day bootstrap methodology (Efron 1979a,b; Hall, 2003).

A stone with a low fractile strength lacks tensile strength and will crack or crumble under stress or pressure.

Most of the three- and four-story white-washed buildings that we passed were built of pink coraline, which is both plentiful and fractile, and date back centuries to when Omanis and Indians based on Zanzibar dominated the African East Coast trade.
