Sample interview questions: How would you approach studying the impact of environmental factors on individuals’ sleep patterns?
Sample answer:
Study Design:
- Longitudinal study: Track individuals over time to observe changes in sleep patterns in relation to environmental changes.
- Cross-sectional comparison: Compare groups of individuals living in different environments with varying environmental factors.
- Experimental design: Manipulate environmental factors (e.g., noise, light) in controlled settings to isolate their impact on sleep.
Data Collection:
- Sleep diaries: Ask participants to record sleep duration, quality, and timing for a specific period.
- Actigraphy: Use wristbands or accelerometers to objectively measure sleep patterns.
- Polysomnography: Conduct sleep studies in laboratories to assess various sleep parameters (e.g., brain activity, eye movements).
- Environmental monitoring: Measure environmental factors (e.g., noise levels, light intensity, temperature) at participants’ residences or workspaces.
Data Analysis:
- Descriptive statistics: Analyze overall trends and correlations … Read full answer
