Sample interview questions: How do you ensure accuracy and validity in your experimental results?
Sample answer:
Accuracy and Validity in Experimental Results
Accuracy:
- Calibrate equipment regularly to minimize measurement errors.
- Use calibrated standards or reference materials to ensure consistency.
- Employ replicate samples and multiple readings to verify results.
- Perform data validation to detect outliers and inconsistencies.
Validity:
- Design experiments with appropriate controls to eliminate confounding variables.
- Use standardized protocols and established techniques to minimize bias.
- Conduct blinded studies or use randomized trials to prevent researcher bias.
- Collect sufficient data to ensure statistical significance and generalizability.
- Collaborate with other scientists and seek externa… Read full answer
