A change in demand versus a change in quantity demanded
A change in demand refers to a shift of the demand curve. A shift occurs if there is a change in one of the variables--other than the price of the product-- that affects the willingness of consumers to buy the product. A change in quantity demanded refers to a movement along the demand curve as a result of a change in the product's price.
If a product's price changed, would this be a change in demand or a change in quantity demanded?
A change in quantity demanded, and would cause movement along the demand curve.
