What's the difference between percentage change and percentage difference?
Percentage CHANGE compares to the original value. Percentage DIFFERENCE compares to the average of both values (used when there's no clear 'original').
Can percentage change exceed 100%?
Yes! If something doubles, that's 100% increase. If it triples, that's 200% increase. Decrease is limited to -100% (total loss).
