A scientist repeats a research study of another scientist or scientists, usually with different participants in different situations, to see whether the original finding extends to other participants and circumstances.

• repetition

• experiment revision

• replication

• control group

The final steps of the scientific method that involves data analysis and reflecting on the results of the experiment and whether or not the hypothesis was correct or not and then submitting it for peer review

• question

• conclusion

• data (results)

• research

Scientific principles

• guiding ideas that scientists use to make predictions and develop new information about the natural world- beliefs about science being fact based not opinion based, the importance of multiple trials, precision in execution of the experimental data, etc

• a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes
