mesokurticadj.

Brit.

/ˌmɛsə(ʊ)ˈkəːtɪk/, U.S.

/ˌmɛzoʊˈkərdɪk/; see also meso- comb. form.

Origin: A borrowing from Greek, combined with English elements. Etymons: meso- comb. form, Greek κυρτός , -ic suffix.

Etymology: < meso- comb. form + ancient Greek κυρτός bulging, convex (see kurtosis n.) + -ic suffix, after mesokurtosis n. Compare K. Pearson's parallel formations platykurtic adj., leptokurtic adj.

Statistics.

Of a frequency distribution or its graphical representation: having the same kurtosis as the normal distribution. Cf. platykurtic adj., leptokurtic adj.

1905 K. Pearson in Biometrika 5 173 Given two frequency distributions which have the same variability as measured by the standard deviation, they may be relatively more or less flat-topped than the normal curve. If more flat-topped I term them platykurtic, if less flat-topped leptokurtic, and if equally flat-topped mesokurtic.

1972 R. B. Cain Elem. Statistical Concepts xix. 159 Any curve which has the same degree of kurtosis as the standard normal curve is said to be mesokurtic.

1979 Nature 7 June 485/1 Sediments are poorly to very poorly sorted and mesokurtic to leptokurtic and samples have a wide range of skewness.

1997 Forest Ecol. & Managem. 93 205 For the youngest stands (40-80 years old) the age distribution was leptokurtic and positively skewed, whereas for middle-aged forests (80-180 years old) it tended to be more mesokurtic and symmetric.
