the answer is repeated trials
repeated trails
The term that describes the practice of conducting tests or experiments more than once to reduce the chance of errors is "replication."
Replication is an important part of the scientific method because it helps ensure the reliability and validity of the results. By performing the same experiment multiple times, scientists can identify any inconsistencies, errors, or random variations that may occur and determine if the results are consistent and can be replicated under different conditions.
Here's how scientists typically conduct replication:
1. Clearly define the experimental design: Scientists need to outline the entire experimental protocol, including variables, controls, and measurement procedures, to ensure consistency across replications.
2. Repeat the experiment: Scientists repeat the exact same experiment, following the defined protocol, multiple times. It is preferable to have a sufficiently large sample size to increase the statistical power of the study.
3. Analyze the results: Scientists analyze the data collected from each replication, looking for patterns, trends, or consistencies in the results.
4. Assess the consistency: By comparing the results of each replication, scientists can assess whether the data is reliable and consistent. If the results vary significantly, it indicates potential errors or inconsistencies in the experimental setup that need to be addressed.
5. Draw conclusions: Based on the consistency of results obtained through replication, scientists can draw valid conclusions about the phenomenon or hypothesis being tested.
Overall, replication is a crucial step in scientific research to ensure that the results are reliable, reproducible, and not simply due to chance. It helps reduce the risk of bias, errors, or anomalies and contributes to the integrity and credibility of scientific findings.
