Which practice aims to minimize bias by standardizing procedures and measurements across all participants?

• A. Randomization
• B. Bias minimization
• C. Blinding when possible
• D. Replication

Answer: (B)

Standardizing how data are collected and measurements are taken for every participant reduces the risk that differences in procedure or evaluator judgment will distort the results. When everyone experiences the same protocols, instruments, thresholds, and scoring criteria, the variation that comes from the measurement process itself is minimized, so any observed differences are more likely to reflect true differences rather than biases in how the data were gathered. This is why bias minimization is the best description of the practice. Randomization helps ensure comparable groups by chance, but it doesn’t inherently standardize measurement procedures across all participants. Blinding reduces bias from expectations but isn’t about making procedures uniform across participants. Replication checks reliability by repeating the study, not the act of standardizing data collection across participants.
