A two-way ANOVA is used when a researcher wants to examine:
Answer: The effect of two independent variables and their interaction on a dependent variable
Two-way ANOVA tests main effects of each of two independent variables and their interaction effect on one dependent variable.
A researcher studying immigrant families uses an interpreter during interviews. A key methodological concern is:
Answer: Potential loss of meaning or nuance in translation affecting credibility
Using interpreters can introduce translation errors that alter participants' intended meanings, threatening qualitative credibility.
In research ethics, the Belmont Report's principle of justice primarily requires that:
Answer: Burdens and benefits of research are distributed fairly across populations
Justice requires equitable selection of participants so that no group bears disproportionate research burdens or is excluded from benefits.
When a researcher uses structural equation modeling (SEM), a primary advantage over standard regression is the ability to:
Answer: Model latent variables and complex causal pathways simultaneously
SEM allows simultaneous estimation of multiple relationships and can model unobserved latent constructs.
A researcher studying adolescent substance use compares outcomes across ethnic groups but does not report effect sizes. This is problematic because:
Answer: Statistical significance alone does not convey the magnitude or practical importance of group differences
Statistical significance is influenced by sample size; effect sizes convey whether group differences are meaningfully large.
The Hawthorne effect refers to the phenomenon in which:
Answer: Participants change their behavior simply because they know they are being observed
The Hawthorne effect is the tendency for people to alter their behavior as a result of being aware that they are being studied.
A researcher reports Cronbach's alpha of 0.91 for a new family resilience scale. This value indicates:
Answer: High internal consistency among scale items
Cronbach's alpha measures internal consistency; values above 0.80 are generally considered good to excellent.
