Sample interview questions: How do you approach designing experiments that investigate the impact of various treatments or interventions on psychological outcomes?
Sample answer:
1. Define the Research Question and Hypotheses:
- Clearly articulate the specific research question and hypotheses to be tested.
- Ensure that the hypotheses are testable, measurable, and based on a sound theoretical framework.
2. Select Appropriate Participants:
- Determine the target population of interest and establish inclusion/exclusion criteria.
- Consider factors such as age, gender, demographic background, and relevant psychological characteristics.
- Recruit a representative sample that is homogeneous within relevant variables.
3. Design the Experimental Protocol:
- Choose an experimental design that allows for causal inferences (e.g., randomized controlled trial, repeated measures design).
- Control for extraneous variables that could confound the results through randomization, counterbalancing, or blind procedures.
- Determine the duration, frequency, and intensity of the treatments or interventions.
4. Develop Measurement and Data Collection Methods:
- Select reliable and valid measures relevant to the research question and outcome variables.
- Consider both quantitative (e.g., questionnaires, behavioral observations) and qualitative (e.g., interviews, focus groups) measures.
- Establish procedures for data collection, including train… Read full answer
