Question 1

A researcher reports a 95% confidence interval of [2.1, 5.8] for a mean difference. This means:

Accepted Answer

If the procedure were repeated, 95% of such intervals would contain the true parameter

Answer

A 95% CI means the interval-construction procedure captures the true parameter in 95% of replications, not that this specific interval has a 95% probability.

Question 2

Demand characteristics in psychological research refer to:

Accepted Answer

Cues that lead participants to guess the study's purpose and alter their behavior

Answer

Demand characteristics are subtle cues in the experimental setting that hint at the study's purpose, potentially altering participant behavior.

Question 3

Which level of measurement allows meaningful ratio comparisons (e.g., 'twice as much')?

Accepted Answer

Ratio

Answer

Ratio scales have a true absolute zero point, allowing meaningful statements about proportional differences between values.

Question 4

In structural equation modeling (SEM), a latent variable is:

Accepted Answer

An unobserved construct inferred from multiple indicators

Answer

Latent variables are unobserved theoretical constructs estimated from patterns among multiple observed indicator variables.

Question 5

Hawthorne effects are a threat to internal validity because:

Accepted Answer

Participants improve simply due to being observed, not the treatment

Answer

The Hawthorne effect occurs when participants change their behavior because they know they are being observed, not because of the experimental manipulation.
