This document discusses kurtosis and leptokurtic and platokurtic distributions. Kurtosis represents the flatness or peakedness of a distribution. A leptokurtic distribution has many scores clustered around the mean and few outlier scores, while a platokurtic distribution has scores evenly spread across all values.

4. Leptokurtic Distributions
In a peaked (leptokurtic) distribution there are
many scores close to the mean with few scores
outlying symmetrically on both sides of the
central tendency.

8. Platokurtic Distributions
In a flat (platokurtic) distribution the scores are
observed rather evenly across all score options.
