Question

a market research company wants to collect opinions on the comfort and performance of a new type of sneaker by brand x. which group of individuals would be the best choice for a random sample?
○ ask every fourth person on the street
○ ask every fourth person who is wearing that brand of sneaker
○ ask every fourth employee from the brand x flagship store
○ ask every fourth person who is wearing shoes

Explanation:

To get unbiased opinions on the new sneaker's comfort and performance, the sample should be as random and representative as possible. Asking every fourth person on the street (first option) includes a diverse group, not limited to sneaker - wearers of that brand, employees, or just shoe - wearers. The second option biases towards Brand X sneaker - wearers, the third towards employees (who may be biased), and the fourth towards shoe - wearers but not necessarily sneaker - wearers or a random cross - section. So the first option is the best random sample.

Answer:

A. ask every fourth person on the street
