Sample interview questions: How do you ensure accuracy and reproducibility of your experimental results?
Sample answer:
-
Use calibrated and standardized equipment: Ensure your instruments, glassware, and measurement devices are properly calibrated and standardized. This helps minimize systematic errors and variations in readings.
-
Follow standardized procedures: Adhere to established protocols and procedures for conducting experiments. This helps ensure consistency in methodology and reduces the chances of errors caused by deviations.
-
Maintain a clean and organized laboratory: A well-maintained laboratory minimizes the risk of contamination, errors, and accidents. Keep your workspace tidy, organized, and free of unnecessary materials or distractions.
-
Record data properly: Keep detailed and accurate records of your experimental procedures, measurements, observations, and calculations. Use a laboratory notebook or electronic data management system to ensure data integrity.
-
Conduct experiments in triplicate or more: Repeating experiments multiple times can help identify and minimize random errors. It also allows you to calculate statistical measures such as standard deviation and average, which provide insights into the precision and reliability of your results.
