3. kurtosis
Kurtosis is a statistical measures, used to
describe the distribution, or skewness.
It observed data around the mean, sometimes
referred to as the volatility of volatility.
Kurtosis is used generally in the statistical field to
describes trends in charts.
Kurtosis can be present in a chart with fat tails
and a low, even distribution, as well as be present
in a chart with skinny tails and a distribution
concentrated toward the mean.

5. Mesokurtic distribution
The first category of kurtosis is
a mesokurtic distribution.
This type of kurtosis is the most similar to a
standard normal distribution in that it also
resembles a bell curve.
However, a graph that is mesokurtic has fatter
tails than a standard normal distribution and has
a slightly lower peak.
This type of kurtosis is considered normally
distributed but is not a standard normal
distribution.

6. Leptokurtic distribution
The second category is a leptokurtic distribution.
Any distribution that is leptokurtic displays
greater kurtosis than a mesokurtic distribution.
Characteristics of this type of distribution is one
with extremely thick tails and a very thin and tall
peak.
The prefix of "lepto-" means "skinny," making the
shape of a leptokurtic distribution easier to
remember.
T-distributions are leptokurtic.

7. Platykurtic distribution
The final type of distribution is a platykurtic
distribution.
These type of distributions have slender tails and
a peak that's smaller than a mesokurtic
distribution.
The prefix of "platy-" means "broad," and it is
meant to describe a short and broad-looking
peak.
Uniform distributions are platykurtic.
