What term refers to the process of repeating a research study with different participants to verify findings?

The correct term that refers to the process of repeating a research study with different participants to verify findings is replication. Replication is an essential aspect of the scientific method as it helps establish the reliability and generalizability of research results. When researchers replicate a study, they seek to determine whether the same results can be observed under similar conditions using different samples. This process helps confirm the findings and strengthens the validity of the original research, as consistency across different populations supports the conclusion drawn from the initial study.

In the context of this question, validity refers to the accuracy of a study's measurements and conclusions but does not specifically denote the act of repeating a study. A sample refers to the group of participants chosen for the study, while a survey is a method of data collection, commonly using questionnaires. None of these terms captures the essence of repeating a research study to verify findings as effectively as replication does.
