I believe a market demand schedule shows how much of a good or service consumers are willing and able to purchase at different prices. It is the tabulation of the quantity of a good that all consumers in a market will purchase at a given price. There is an inverse relationship between the price and the quantity demanded, such that increase in the price causes a decrease in demand while decrease in price causes an increase in demand.
