Question

Question 4
A candy manufacturer conducts a survey to learn more about its customer base. Although young people are known to purchase a large percentage of its candy, due to age requirements, the survey is only sent to customers who are 18 years or older. What is likely to result?


Geographically limited sampling



Random sampling



Unbiased sampling



Sampling bias

Answer 1

Sampling bias — excluding under-18 customers (who buy a large share of the candy) produces a nonrepresentative, biased sample.
