When the tails of a distribution are fatter than that implied by a normal distribution, we say that the distribution is:
　　A. platykurtic.
　　B. symmetrical.
　　C. skewed.
　　D. leptokurtic.
　　Answer:D
　　When the tails of a distribution are thicker than that of a normal distribution, we say that the distribution is leptokurtic. Platykurtic means that the tails are thinner than normal. The size of the tails is not indicative of a distribution’s symmetry. Rather, the presence of skewness indicates that the distribution is not symmetrical.
