Swift Research & Evidence-Based Practice 4

Question 1

Effect size in research is important because it indicates:

Accepted Answer

The practical magnitude of an observed difference or relationship

Answer

Effect size quantifies the practical or clinical significance of findings, separate from statistical significance, by showing how large the difference or association is.

Question 2

A researcher conducting a grounded theory study collects data until no new themes emerge. This is called:

Accepted Answer

Theoretical saturation

Answer

Theoretical saturation occurs when continued data collection yields no new categories or insights, signaling sufficient data for theory development.

Question 3

Which research design is BEST suited to establish cause-and-effect relationships?

Accepted Answer

Randomized controlled trial

Answer

RCTs use random assignment to control groups, allowing researchers to attribute changes in outcomes directly to the intervention rather than confounding variables.

Question 4

Triangulation in qualitative research refers to:

Accepted Answer

Using multiple data sources or methods to enhance trustworthiness

Answer

Triangulation increases credibility by cross-verifying findings through multiple data sources, methods, investigators, or theoretical perspectives.

Question 5

A social work researcher finds that wealthier neighborhoods have more mental health clinics AND lower rates of depression. What is the most appropriate conclusion?

Accepted Answer

There is a correlation, but causation cannot be established

Answer

Correlational data cannot establish causation; observed associations may be due to confounding variables or reverse causality.
