Which concept is used in research to make sure that different scientists who are exploring the same concept are able to conduct a true replication of the original experiment?
A) Theories
B) Observer-expectancy controls
C) Operational definitions
D) Null hypotheses

Question

Operational definitions are used in research to define and describe concepts in a specific and measurable way, which allows for accurate and consistent replication of experiments by different scientists. By using operational definitions, researchers can ensure that their findings are valid and reliable, and that they can be replicated by other scientists. The other options, such as theories and null hypotheses, are also important in research, but they do not specifically address the issue of replication and consistency across multiple experiments. Observer-expectancy controls are techniques used to minimize experimenter bias, but they are not directly related to replication of experiments.
