In a survey of consumers in an Eastern European nation, respondents were asked two questions about each of 400 famous Western brands, whether or not, they recognized the brand name and whether or not they thought the products bearing that name were of high quality. The results of the survey were a rating and corresponding rank order for each brand based on recognition, and a second rating- plus- ranking based on approval. The brands ranked in the top 27 for recognition were those actually available in that nation. The approval rankings of these 27 brands often differed sharply from their recognition rankings. By contrast, most of the other brands had ratings, and thus rankings, that were essentially the same for recognition as for approval.
Which one of the following, if each is a principle about consumer surveys, is violated by the survey described?
A) Never ask all respondants a question if it cannot reasonably be answered by respondants who make a particular response to another question in the same survey.
What exactly does this mean?
This means that you shouldn't ask a question that can or cannot be answered based on the answer to another question in the same survey.
For example: one of the questions asked is "do you think products of this brand are of high quality?" However, this question obviously cannot be answered if the answer to the other question "Do you recognize this brand?" is NO.
