A distribution that has positive excess kurtosis is:

A) more skewed than a normal distribution.

B) less peaked than a normal distribution.

C) more peaked than a normal distribution.

A distribution of returns that has a greater percentage of small deviations from the mean and a greater percentage of large deviations from the mean compared to a normal distribution:

A) is positively skewed.

B) has positive excess kurtosis.

C) has negative excess kurtosis.

A distribution of returns that has a greater percentage of small deviations from the mean and a greater percentage of large deviations from the mean compared to a normal distribution:

A) is positively skewed.

B) has positive excess kurtosis.

C) has negative excess kurtosis.

---

A distribution that has a greater percentage of small deviations from the mean and a greater percentage of large deviations from the mean will be leptokurtic and will exhibit positive excess kurtosis. The distribution will be taller (more peaked) with fatter tails than a normal distribution.

Which of the following statements concerning a distribution with positive skewness and positive excess kurtosis is least accurate?

A) It has a lower percentage of small deviations from the mean than a normal distribution.

B) The mean will be greater than the mode.

C) It has fatter tails than a normal distribution.

Which of the following statements concerning a distribution with positive skewness and positive excess kurtosis is least accurate?

A) It has a lower percentage of small deviations from the mean than a normal distribution.

B) The mean will be greater than the mode.

C) It has fatter tails than a normal distribution.

---

A distribution with positive excess kurtosis has a higher percentage of small deviations from the mean than normal. So it is more “peaked” than a normal distribution. A distribution with positive skew has a mean > mode.

bmaggie

Which of the following statements concerning kurtosis is least accurate?

A) A distribution that is more peaked than a normal distribution is leptokurtic.

B) A leptokurtic distribution has fatter tails than a normal distribution.

C) A leptokurtic distribution has excess kurtosis less than zero.

---

A leptokurtic distribution is more peaked than normal and has fatter tails. However, the excess kurtosis is greater than zero.

Which of the following statements about kurtosis is least accurate? Kurtosis:

A) measures the peakedness of a distribution reflecting a greater or lesser concentration of returns around the mean.

B) describes the degree to which a distribution is not symmetric about its mean.

C) is used to reflect the probability of extreme outcomes for a return distribution.

B) describes the degree to which a distribution is not symmetric about its mean.

C) is used to reflect the probability of extreme outcomes for a return distribution.

---

The degree to which a distribution is not symmetric about its mean is measured by skewness. Excess kurtosis which is measured relative to a normal distribution, indicates the peakedness of a distribution, and also reflects the probability of extreme outcomes.

Which of the following statements concerning skewness is least accurate? A distribution with:

A) a distribution with skew equal to 1 is not symmetrical.

B) positive skewness has a long left tail.

C) negative skewness has a large number of outliers on its left side.

---

A distribution with positive skewness has long right tails.

A) A distribution that is more peaked than a normal distribution is leptokurtic.

B) A leptokurtic distribution has fatter tails than a normal distribution.

C) A leptokurtic distribution has excess kurtosis less than zero.
