Definitions:

Dependent

In statistics, a variable whose value depends on the influence or measurement of another variable.

Proportion

A statistical measure that represents the fraction of the total number of outcomes in a given category relative to the total number of outcomes in all categories.

Observations

Data collected or measured during an experiment or survey. They are the individual values recorded during the statistical study.

Fair Die
