Skewed

A description of a distribution that is not symmetrical around its mean, indicating that the data points tend to extend more to one side than the other.

Normally Distributed

Refers to a probability distribution that is symmetrically shaped around the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Mean

The arithmetic average of a set of numbers, calculated by adding them all together and dividing by the count of these numbers.

Right-Skewed
