CARS CARS Evidence Evaluation and Research Methods

Question 1

A CARS passage states that a study found a correlation between coffee consumption and improved memory. What is the most important limitation to consider when evaluating this claim?

Accepted Answer

Correlation does not establish causation

Answer

Correlation between two variables does not prove that one causes the other, as a third confounding factor may be responsible.

Question 2

In a CARS passage, an author cites a single case study to support a broad universal claim. Which type of reasoning error does this represent?

Accepted Answer

Hasty generalization

Answer

Hasty generalization occurs when a sweeping conclusion is drawn from insufficient or unrepresentative evidence.

Question 3

A CARS passage describes a double-blind study. What does 'double-blind' mean in this context?

Accepted Answer

Neither participants nor researchers know who received the treatment

Answer

In a double-blind study, neither the participants nor the researchers administering the treatment know who is in the control or experimental group, reducing bias.

Question 4

An author in a CARS passage uses only peer-reviewed journal articles published within the last five years to support an argument. What does this suggest about the evidence?

Accepted Answer

The evidence is current and has undergone expert scrutiny

Answer

Peer-reviewed, recent sources indicate the evidence has been vetted by experts and reflects current knowledge, though it still requires critical evaluation.

Question 5

A CARS passage presents a study where the sample consisted entirely of college students. What methodological concern does this raise?

Accepted Answer

The findings may not generalize to broader populations

Answer

A sample limited to college students may not represent the full diversity of the population, limiting the external validity of the findings.
