Definitions:

Positively Skewed

Describes a distribution of data where the tail on the right side of the frequency distribution is longer than the left side, indicating that most values are clustered around the left.

Median

A statistical measure representing the middle value in a sorted, listed version of a set of numbers, effectively splitting the data set into two halves.

Mean

The average value of a set of numbers, calculated by dividing the sum of all the values by the number of values.

Symmetric

Characteristic of a shape or figure that is identical on both sides of a central line; it applies broadly to situations where two sides of something are mirror images of each other.
