peakedness
Noun
Meaning
(chiefly in combination) The condition of having a (specified form of) peak
(statistics) kurtosis (archaic).
Source: en.wiktionary.orgExamples
Many incorrect interpretations of kurtosis that involve notions of peakedness have been given.
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."
