Terms to Know
Interval Measurement

A type of measurement for quantitative data where the value of zero does not correspond to the absolute minimum value, and therefore values cannot be compared in terms of "double," "triple," "half," or any other multiplier. We can, however, compare the differences between values.

Ratio Measurement

A type of measurement for quantitative data where the value of zero is the absolute minimum. Because of this, numerical values that are twice as high represent twice as much.
