Question 9

Which of the following is a common technique used in qualitative synthesis?

Accepted Answer

Thematic analysis

Answer

Meta-analysis

Answer

Regression analysis

Answer

Cronbach's alpha

Question 10

What is the primary purpose of assessing heterogeneity in research synthesis?

Accepted Answer

To determine the consistency of findings across studies

Answer

To identify potential biases or external validity threats

Answer

To calculate the overall effect size

Answer

To develop recommendations for future research

Question 11

What is the primary purpose of a meta-analysis?

Accepted Answer

To combine the results of multiple studies to provide a more precise estimate of an effect

Answer

To identify potential publication bias

Answer

To assess the quality of individual studies

Answer

To develop new research hypotheses

Question 12

What is the advantage of using a qualitative synthesis approach over a quantitative synthesis approach?

Accepted Answer

It allows for the exploration of complex and context-dependent phenomena

Answer

It provides more precise estimates of effect sizes

Answer

It is less time-consuming and requires less resources

Answer

It is more suitable for experimental studies

Question 13

How does the choice between fixed-effects and random-effects models influence the interpretation of meta-analysis results?

Accepted Answer

Fixed-effects models assume study homogeneity, while random-effects models consider study heterogeneity.

Accepted Answer

Random-effects models tend to be more conservative, resulting in broader confidence intervals compared to fixed-effects models.

Answer

The choice of meta-analytic technique has no bearing on the interpretation of results.

Answer

Fixed-effects models are always superior to random-effects models.
