1. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.

2. According to the essay, how were stories first communicated and passed down?

• A. oral tradition
• B. printed books
• C. technology
• D. handwriting

Correct answer: A

Rationale: The essay clearly states that before the invention of the printing press, stories were passed down through oral tradition. The extract mentions, 'For centuries before the invention of the printing press, stories of the world were passed down to generations through oral tradition.' This shows that oral tradition was the primary method of communicating stories before the introduction of printed books. Therefore, the correct answer is 'oral tradition.' Printed books (choice B) were introduced later with the invention of the printing press, as mentioned in the extract. 'Handwriting' (choice D) is not the first way stories were communicated, and 'technology' (choice C) is a broad term that does not specifically refer to the initial method of story communication.

3. Which of the answer choices best describes the appropriateness of Mara's data sample?

• A. The sample is biased because it only includes teachers who are immersed in the technology field.
• B. The sample is biased because the sample size is too small.
• C. The sample is biased because the sample size is too large.
• D. The sample is not biased and is appropriate for the study.

Correct answer: A

Rationale: The correct answer is A. Mara's data sample is biased because it only includes teachers who are immersed in the technology field, specifically those teaching a computer software course. This limits the perspectives gathered, leading to skewed results. Choice B is incorrect because the issue lies in the sample composition, not its size. Choice C is incorrect as a large sample size does not necessarily indicate bias. Choice D is incorrect as the sample's bias compromises the study's validity.

4. Which of the following sources is most likely to provide relevant data on the effects of mobile use on consumers' hearing?

• A. A consumer report about surcharges applied to customers' bills by mobile phone companies
• B. A professional journal article about the incidence of generic hearing loss
• C. A university research paper about decibel limits of headphones and speakers
• D. A statistical report of mobile phone usage by a mobile phone company

Correct answer: C

Rationale: The most relevant source for data on the effects of mobile use on consumers' hearing would be a university research paper about decibel limits of headphones and speakers. This source would provide specific information on how mobile use could potentially impact hearing due to the sound levels produced by headphones and speakers. Choice A discusses surcharges on bills, which is unrelated to hearing effects. Choice B focuses on the incidence of hearing loss in general, not specifically related to mobile use. Choice D, a statistical report on mobile phone usage, may not directly address the impact on consumers' hearing.

5. When evaluating the credibility of research sources, which of the following is a valid consideration?

• A. It is credible if published in a peer-reviewed scholarly journal.
• B. It is never credible if it is a source published online.
• C. It is not necessarily more credible based on author affiliations.
• D. The number of times a source is cited does not affect its credibility.

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.
