In a frequency distribution, the sharply peaked kurtosis is known as :

  • A.Micro-kurtic distribution
  • B.Meso-kurtic distribution
  • C.Platy-kurtic distribution
  • D.Lepto-kurtic distribution

Answer: D

A sharply peaked distribution is leptokurtic.

Kurtosis describes the peakedness of a frequency curve compared with the normal curve. A curve more peaked than normal, with values concentrated near the mean, is leptokurtic (kurtosis greater than 3). The normal curve itself is mesokurtic, and a flatter curve is platykurtic.

'Micro-kurtic' is not a term used for kurtosis, so it and the other two options do not describe a sharply peaked distribution.
