a. What is wrong with this survey?

Accepted Answer

All right, hello, everyone. So this question said that a health magazine conducted an online survey asking, quote, should people reduce their daily sugar intake, end quote. Of the 1320 respondents who chose to participate, 78% answered yes. What is wrong with this survey? Option A says the survey is flawed because it does not allow respondents to explain their answers. B says the survey is biased because only people who consume high amounts of sugar were surveyed. She says the survey is invalid because the sample size is too small. And D says the survey results are unreliable because they're based on voluntary responses. So, before we discuss the correct answer in greater detail, there's one thing that I want to point out about one of the answer choices listed here, and that's option B, right? Because option B states that the survey is biased because only people who consume high amounts of sugar were surveyed. We don't actually know that, right? We don't actually know about the sugar consumption habits of the participants, so I'm going to go ahead and cross off option B. Now let's talk about the survey itself. Well, first and foremost, the survey is being conducted by a health magazine. And Viewers, people that are reading the magazine online, can choose to participate in the survey if they want to, right? In this case, we had over 1300 people that chose to do so. That right there introduces a potential bias, right? So I'm writing here on the screen, voluntary response bias as a potential issue with the survey, right? Because what happens is that by relying on people that choose to participate themselves. Only those that that feel more strongly about the topic are more likely to respond, which can skew the results. Now, on that note, right, the voluntary response bias also introduces a lack of random sampling. Which makes it difficult for the results of the survey to truly represent the greater population. Right, because here The survey isn't randomly selecting people from the population, rather, it's allowing those people to choose to participate in the survey, meaning that that won't always accurately reflect the opinions of all people. And last but not least, you have to consider the sample size to begin with or. What types of people make up the sample size, right? And here, right, the only people that are answering the survey are those that have access to the magazine online. So here, people that don't read the magazine's online version or are simply not interested in the topic may be excluded altogether, which again is another reason why the sample isn't representative of the greater population. So there are multiple different factors that we discussed here that affect the valid validity of the survey, but Out of the answer choices that were given, the correct one in this case is going to be option D in the multiple choice, because the survey results are unreliable because they are based on voluntary responses. And there you have it. So with that being said, thank you so very much for watching, and I hope you found this helpful.
