Which term describes an experiment that produces similar results each time it is conducted?

The term that best describes an experiment that produces similar results each time it is conducted is "reliable." Reliability in the context of experiments refers to the consistency of the results when the experiment is repeated under the same conditions. A reliable experiment yields outcomes that are reproducible, meaning that if the same procedures and conditions are followed, similar results should be obtained each time.

This consistency is crucial in scientific experimentation as it supports the credibility of the findings. Reliable results enhance confidence in the conclusions drawn from the experiment, suggesting that the observations are not simply due to randomness or external variability.

While "consistent" may seem similar, it lacks the specific emphasis on the dependable nature of the results that "reliable" conveys in a scientific context. Similarly, "reliability" is related but refers more to the overall concept of consistent performance rather than describing the specific results of an experiment. The term "variable" refers to any factor that can change or be manipulated in an experiment and does not pertain to the reliability of the outcomes. Hence, "reliable" is the most suitable choice for describing the characteristic of an experiment yielding similar results consistently.
