Question

Imagine a class where nearly everyone scores between 83-84%, with hardly any dispersion beyond this narrow peak. How would you describe this distribution in terms of kurtosis?

Answer 1

The given distribution is leptokurtic.

Here, the proportion of observations around the mode is more, therefore the distribution curve will exhibit sharper peak or higher peak than normal distribution. The distribution having more peak than the normal distribution, is called as leptokurtic distribution.
