Study Notes
Experiment Design
- Researcher wants to see if a new training program impacts employee productivity.
- Independent variable: Training program
- Dependent variable: Employee productivity
- Control group should not receive the training for a valid comparison.
- Measure productivity before, during and after training to track progress.
- Randomly assign employees to either the training group or the control group.
- Data collection methods should include standardized metrics (e.g., output quantity, quality, error rate).
- Researcher needs to control for other factors that could influence productivity (e.g., experience level, workload, work environment).
- Statistical analysis (e.g., t-tests, ANOVA) can compare productivity differences between groups.
