In statistics, describing a distribution that differs in peakedness or kurtosis from a reference distribution, with either sharper or flatter peaks than normal.
From Greek 'allo-' (other) + 'kurtos' (curved, convex); a statistical term from 20th-century mathematics comparing the shape of probability distributions.
When data looks 'spiky' with extreme outliers (like test scores where some students ace it and others bomb it), statisticians call that allokurtic, and it tells you whether the phenomenon is more predictable or chaotic than usual!
