Definitions:

Standard Deviation

A measure of the amount of variation or dispersion in a set of values, indicating how spread out the values are from the mean.

Poisson Random Variable

Represents the number of events occurring within a fixed interval of time or space, assuming these events happen at a constant rate and independently of the time since the last event.

Expected Value

The expected value is the long-run average value of repetitions of an experiment it represents, often used in probability and statistics.

Poisson Distribution

A probability distribution that represents the likelihood of observing a certain number of events within a specified time or space interval.
