Roshan ZameerDifference between change quantity demand and change in demand
One is movement along the curve and another is shift of the curve. If there is a change in Qty demanded there will be a change in price i.e movement along the curve. Change in demand is when there is a shift in curve i.e at same price point qty demanded is now more that what it was earlier or less than what it was earlier
