Definitions:

Positively Skewed

A positively skewed distribution is one in which most of the data points are concentrated on the left, with the tail extending to the right.

Negatively Skewed

Describes a distribution of values where the tail on the left side of the probability density function is longer or fatter than the right side, indicating a majority of the data lies to the right of the mean.

Frequency Polygon

Line graph that uses data points to represent the frequency of each value of a variable.

Skewed Distribution

A distribution where the tails on one side of the mean are longer or fatter, indicating lack of symmetry.
