Noun
(chiefly in combination) The condition of having a (specified form of) peak
(statistics) kurtosis (archaic).
Source: en.wiktionary.orgMany incorrect interpretations of kurtosis that involve notions of peakedness have been given. Source: Internet
This example makes it clear that data near the "middle" or "peak" of the distribution do not contribute to the kurtosis statistic, hence kurtosis does not measure "peakedness." Source: Internet
