Quizplus · Accepted Answer

A change in quantity demanded refers to a movement along the demand curve in response to a change in the price of the good. On the other hand, a change in demand means the entire demand curve shifts, either to the right (increase in demand) or to the left (decrease in demand), due to a change in any variable other than price that affects buyers' willingness and ability to purchase the good.
