Incorrect

The question was: What are such "heavy tailed" distributions are called?

Answer and explanation: Your answer is incorrect. The correct answer is "leptokurtic." "Kurtosis" the amount of data in the tails of a distribution. A leptokutic ditribution has more data in the tails (like the outliers shown in each of the 4 groups) than a normal distribtions does.

Platykurtosis is the opposite of leptokurtosis. A platykurtic distribution has less data in the tails of the distribution than a normal distribution would.
