Understanding Demand and Quantity Demanded

The video tutorial explains the difference between a change in quantity demanded and a change in demand. A change in quantity demanded is a movement along a fixed demand curve due to price changes, while a change in demand is a shift in the demand curve caused by factors like income or preferences. The tutorial uses examples to illustrate these concepts and provides guidance on how to identify shifts in the demand curve. It concludes with a summary and additional resources for further learning.

What is the primary cause of a change in quantity demanded?

• A change in the price of the good

• A change in the price of related goods

• A change in consumer income

• A change in consumer preferences

When the price of sugary fizzy drinks increases from $3 to $4, what happens to the quantity demanded?

• It remains the same

• It increases

• It doubles

• It decreases

Which of the following would cause a movement along the demand curve?

• A change in consumer preferences

• A change in the price of related goods

• A change in the price of the good

• A change in consumer income

What can cause a shift in the demand curve for sugary fizzy drinks?

• A decrease in the supply of sugary fizzy drinks

• A change in the price of sugary fizzy drinks

• A change in the production cost of sugary fizzy drinks

• A viral marketing campaign for a substitute product

What is the effect of a viral marketing campaign for a substitute product on the demand for sugary fizzy drinks?

• It increases the demand

• It has no effect on the demand

• It decreases the demand

• It doubles the demand

How does a decrease in demand affect the demand curve?

• It has no effect on the curve

• It shifts the curve up and to the right

• It shifts the curve down and to the left

• It causes movement along the curve

What is the difference between a change in demand and a change in quantity demanded?

• Both are movements along the curve

• A change in demand is a shift of the curve, while a change in quantity demanded is a movement along the curve

• A change in demand is a movement along the curve, while a change in quantity demanded is a shift of the curve

• Both are shifts of the curve

Which of the following is NOT a factor that can shift the demand curve?

• Price of the good itself

• Population changes

• Consumer preferences

• Consumer income

Which axis represents price in a demand curve graph?

• Horizontal or x-axis

• Vertical or y-axis

• Diagonal axis

• None of the above

What happens to the demand curve when there is a change in a variable not measured on the axes?

• There is movement along the curve

• The curve remains unchanged

• The curve shifts

• The curve disappears
