• Skewness

• Standard Deviation

• Kurtosis

• Central Tendency

It is a distribution with a positive kurtosis which has more in its tails than the normal distribution.

• Mesokurtic

• Leptokurtic

• Platykurtic

• None of the above

Given that the calculated kurtosis is 2.49, what kind of distributional peakedness does the frequency curve show?

• Mesokurtic

• Leptokurtic

• Platykurtic

• None of the above

It is a normal distribution curve that is neither too flat nor has a disproportionately high curve or peak.

• Mesokurtic

Using the fourth moment about the mean, the computed kurtosis is 1.29.
