Which term describes how a quantity changes in relation to another group?

Explanation:
Relative change describes how a quantity changes in relation to its starting point or a reference group. It measures the difference as a proportion of the initial value, usually expressed as a percentage. The idea is to see not just how much the quantity moved, but how big that move is relative to where it began. For example, if a group increases from 100 to 120, the relative change is (120 − 100) / 100 = 0.20, or 20%. If you compare two groups, you can compute the relative change for each and compare which one increased more in proportion, not just in absolute amount. The other terms are not about describing change relative to a baseline or reference group, so they don’t fit the concept.
