Accepted Answer

Test-retest reliability

Test-retest reliability measures the stability of scores over time by correlating results from two administrations of the same instrument.

Question 2

In a causal-comparative (ex post facto) research design, the primary limitation compared to a true experiment is:

Accepted Answer

Lack of control over the independent variable and random assignment

Answer

Because the independent variable has already occurred and participants were not randomly assigned, causal-comparative designs cannot definitively establish causation.

Question 3

Which qualitative approach would be most appropriate for a researcher studying how a single urban high school implements a new trauma-informed policy over one semester?

Accepted Answer

Case study

Answer

Case study is ideal for an in-depth investigation of a single bounded system (the school) within its real-world context over a defined period.

Question 4

A researcher conducting a focus group on student mental health services must be especially attentive to which ethical concern unique to group settings?

Accepted Answer

Confidentiality among participants

Answer

In focus groups, the researcher cannot guarantee that other participants will keep shared information confidential, making it a unique ethical challenge compared to individual interviews.

Accepted Answer

Multiple regression analysis

Multiple regression allows the researcher to examine the predictive relationship between professional development and achievement while statistically controlling for socioeconomic status.
