Percentage Points vs Percent Change
A small wording difference can turn 5% into 50%.
What it does and when to use it
Moving from 10% to 15% is an increase of 5 percentage points but a relative increase of 50%. Both are correct and mean different things.
What information to enter
Identify the original value, new value, and whether the question asks for an absolute rate difference or a relative change.
How to understand the result
Percentage points compare rates directly; percent change measures change relative to the starting value.
