Definitions:

Interval Measures

A scale of measurement where the difference between any two consecutive measures is the same, but it does not have a true zero point, e.g., temperature scales.

Equal Intervals

A measurement scale where the difference between values is the same across the scale.

True Zero

A point on a scale which represents a complete absence of the measured entity, not merely an arbitrary point.

Powerful

Having great control, influence, or effect on others or outcomes.
