Which of the following is an example of a Type II error in research?
Answer: Failing to reject a false null hypothesis
A Type II error (beta error) occurs when the researcher fails to reject a null hypothesis that is actually false -- in other words, missing a real effect that exists in the population.
A researcher wants to understand the lived experiences of counselors-in-training who experienced imposter syndrome. Which research methodology is MOST appropriate?
Answer: Phenomenological qualitative research
Phenomenological research is designed to describe and understand the essence of lived experiences from the participants' perspectives, making it ideal for exploring subjective experiences like imposter syndrome.
In program evaluation, 'formative evaluation' is conducted:
Answer: During the program to provide feedback for improvement
Formative evaluation occurs during program implementation to monitor progress and provide ongoing feedback that can improve the program while it is still running. Summative evaluation assesses final outcomes.
Which statistical test is appropriate for comparing the mean scores of two independent groups on a continuous outcome variable?
Answer: Independent samples t-test
The independent samples t-test compares the means of two independent groups (e.g., treatment vs. control) on a continuous dependent variable. It tests whether the difference between group means is statistically significant.
The concept of 'triangulation' in qualitative research refers to:
Answer: Using multiple data sources, methods, or investigators to enhance credibility
Triangulation involves using multiple sources of data, methods, theoretical frameworks, or investigators to cross-check findings and increase the trustworthiness and credibility of qualitative research.
When a counselor researcher reviews all published studies on the effectiveness of CBT for depression and statistically combines their results, this is called:
Answer: A meta-analysis
A meta-analysis statistically combines the results of multiple independent studies to calculate an overall effect size, providing the highest level of evidence about treatment effectiveness.
