Answer:
- Change in quantity demanded: Represent a change of total demands of a product that is caused by the price of the product.
When the price of a product increased, the amount of consumers who can afford to buy that product is decreased, As a result, this cause a decrease in overall demand over that product. (The opposite happened when the price of product is decreased)
- a shift in the demand curve. : Represent a change of total demands of a product that is caused by other factors beside the price of the products.
Price is not the only one that can affect demands. For example, natural disaster could occurred and make a certain type of product become really scarce. This tend to lead to an increase of demand even if the price of that product remain the same.
Observational methods, case-study methods and survey methods.
Observational Method
With the observational method (sometimes referred to as field observation) animal and human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
Case Study Method
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
Survey Method
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.
