MFT Research Methods 5

Question 1

A two-way ANOVA is used when a researcher wants to examine:

Accepted Answer

The effect of two independent variables and their interaction on a dependent variable

Answer

Two-way ANOVA tests main effects of each of two independent variables and their interaction effect on one dependent variable.

Question 2

A researcher studying immigrant families uses an interpreter during interviews. A key methodological concern is:

Accepted Answer

Potential loss of meaning or nuance in translation affecting credibility

Answer

Using interpreters can introduce translation errors that alter participants' intended meanings, threatening qualitative credibility.

Question 3

In research ethics, the Belmont Report's principle of justice primarily requires that:

Accepted Answer

Burdens and benefits of research are distributed fairly across populations

Answer

Justice requires equitable selection of participants so that no group bears disproportionate research burdens or is excluded from benefits.

Question 4

When a researcher uses structural equation modeling (SEM), a primary advantage over standard regression is the ability to:

Accepted Answer

Model latent variables and complex causal pathways simultaneously

Answer

SEM allows simultaneous estimation of multiple relationships and can model unobserved latent constructs.

Question 5

A researcher studying adolescent substance use compares outcomes across ethnic groups but does not report effect sizes. This is problematic because:

Accepted Answer

Statistical significance alone does not convey the magnitude or practical importance of group differences

Answer

Statistical significance is influenced by sample size; effect sizes convey whether group differences are meaningfully large.
