What term refers to a duplicate trial that mirrors the original experiment?

• A. Control
• B. Data
• C. Experiment
• D. Replicate

Answer: (D)

The idea being tested is replication of trials to verify results. A replicate is a duplicate trial run under the same conditions, designed to mirror the original experiment and see if the results hold steady. Replicates help reveal whether findings are reliable or just due to random variation, by showing consistent outcomes across repeated trials. If results are similar across replicates, confidence in the conclusion increases; if they vary, it may indicate uncontrolled variables or measurement error. A control is a baseline for comparison, not a duplicate trial. Data are the measurements collected, not the act of repeating the experiment. An experiment is the overall investigation, including the setup and procedures, not specifically a duplicate trial.
