Sample interview questions: How do you ensure accuracy and reliability in your experimental data?
Sample answer:
Data Integrity Measures:
-
Calibrating Instruments: Regular calibration ensures instruments meet accuracy specifications.
-
Controlling Variables: Identifying and controlling factors that could influence results, such as temperature or humidity.
-
Multiple Measurements: Repeating measurements under the same conditions provides redundant data for statistical analysis.
Data Analysis Methods:
-
Statistical Analysis: Using appropriate statistical techniques to calculate mean, standard deviation, and confidence intervals.
-
Cross-Validation: Validating results using different data sets or analysis methods to assess reliability.
-
Error Analysis: Quantifying and understanding sources of uncertainty, such as instrumental error or background noise.
