Evaluating Evidence Flashcards

What is the most reliable source of evidence for a scientific argument?

Answer: Peer-reviewed research articles

Peer-reviewed research articles are considered the most reliable source of scientific evidence because they undergo a rigorous evaluation process by other experts in the field. This process ensures that the methodology is sound, the data is accurately interpreted, and the conclusions are supported by evidence, thereby enhancing the credibility and validity of the research.

Which of the following weakens the credibility of evidence in a text?

Answer: The source is an anonymous blog.

An anonymous blog lacks accountability, verifiable authorship, and often, expert review. Evidence from such a source is inherently unreliable because there's no way to confirm the author's qualifications, potential biases, or the accuracy of the information presented. This significantly weakens the credibility of any claims made.

How can you determine if evidence is relevant to an argument?

Answer: It supports the conclusion directly or indirectly.

Evidence is relevant to an argument if it directly or indirectly supports the conclusion or claims being made. It must provide information that helps to prove, illustrate, or strengthen the argument's central point. Irrelevant evidence, regardless of its presentation or complexity, does not contribute to the argument's validity.

A passage cites data from 2002 to support a claim about current technology trends. Why might this evidence be considered weak?

Answer: The data is outdated.

For claims about current technology trends, data from 2002 is significantly outdated. Technology evolves rapidly, so information from two decades ago would not accurately reflect present-day developments or trends. Using old data weakens the argument by failing to provide current and pertinent support for the claim.

Which of the following strengthens the evidence presented in an argument?

Answer: The evidence comes from multiple reputable sources.

Evidence is significantly strengthened when it comes from multiple reputable sources. This corroboration indicates that the information is consistent and reliable, reducing the likelihood of bias or error from a single source. Reputable sources are generally recognized for their expertise, objectivity, and thoroughness in research.
