Ratio

Ratio scales contain order, exact values, and absolute zero, which makes it possible to be used in descriptive and inferential statistics. These scales provide numerous possibilities for statistical analysis. Mathematical operations, the measure of central tendencies, and the measure of dispersion and coefficient of variation can also be computed from such scales.  

Examples include a measure of energy, mass, length, duration, electrical energy, plan angle, and volume. The following table gives a summary of the data types and scale measures:

In the next section, we will compare EDA with classical and Bayesian analysis.
