More accurate is
Percentage change
= ...
= -87.5%
rather than
percentage decrease
= ...
= -87.5%
Percentage change
= ...
= -87.5%
rather than
percentage decrease
= ...
= -87.5%
True that. Thus, in terms of percentage change, a negative sign indicates a percentage decrease. Positive sign a percentage increase.
