Ensuring data accuracy involves multiple steps: - Calibration: Regular calibration of instruments is essential to maintain accuracy. Use standard reference materials for calibration. - Replication: Conducting multiple trials of the same experiment helps in verifying the consistency of the results. - Standard Operating Procedures (SOPs): Following SOPs minimizes variability and ensures that experiments are conducted in a standardized manner. - Data Validation: Cross-checking data with theoretical models or literature values can help in identifying anomalies.
