The share of a party in the polls goes from 20 % to 25 %. By how many percentage points does it change (absolute value)?
Answer and explanation
Correct answer: D. 5
- Step 1: The change in percentage points is the simple difference of the two rates. Step 2. 25 - 20 = 5, so the change is 5 points. Answer: 5. Why not the others: 25: this is the relative change, not the change in points. 45: the rates were added. 10: the difference was doubled.
