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
Answer
Brief Explanations:
A good random sample should be representative of the general population of potential sneaker - wearers. Asking every fourth person on the street is likely to capture a diverse group of people who may or may not be wearing Brand X sneakers, but are part of the general public that could potentially buy and use the sneakers. Asking only those wearing the brand may lead to a biased sample (they already like the brand), asking store employees is not representative of consumers, and asking only those wearing shoes is too broad and not focused on potential Brand X customers.
Answer:
ask every fourth person on the street
