A market research sample should be representative of all the people in the market. Which option best reflects this requirement?

• A. Only the richest customers.
• B. Only people in one city.
• C. All market participants.
• D. All market participants including suppliers.

Answer: (D)

Representativeness means the sample should reflect every group that makes up the market, not just a single segment. If you only ask the richest customers or people from one city, you’d get a biased picture that misses regional differences and the needs of other customers. Including all market participants, including suppliers, broadens the view to cover the whole market environment—the buyers who buy the product and the suppliers who affect its availability, price, and quality. This fuller range helps ensure the findings apply more generally to the market as a whole.
