	Percentiles are often used in classifying extremes of statistics in various [[climate]] situations. For example, a daily [[temperature]] is classified as ''extreme'' when that day's high (or low) is in the 90th percentile of the same day in previous years.<ref name=IPCC_SREX/>		Percentiles are often used in classifying extremes of statistics in various [[climate]] situations. For example, a daily [[temperature]] is classified as ''extreme'' when that day's high (or low) is in the 90th percentile of the same day in previous years.<ref name=IPCC_SREX/>

	Values can also be separated into groups known as ''deciles'' and ''quartiles'' ~~- deciles~~ split the data into tens while quartiles split it into quarters. From the earlier example, Jill would be in the upper quartile as she is taller than over 75% of the other people, and would be in the 8th decile.<ref name=math/>		Values can also be separated into groups known as ''deciles'' and ''quartiles.'' Deciles split the data into tens while quartiles split it into quarters (fours).
