Not considering all possible outcomes can lead to bias. In a physics lab students are conducting an experiment to learn about The velocity when the engine stops power is vE = v0 + a (tE). The hypothesis of an experiment should be hidden from the participants so they don't act in favor or maybe against it. Now, that you have a better idea of the terminology involved in conducting an experiment, you can define the meaning of conducting an experiment as follows: Conducting an experiment is the process where researchers manipulate an explanatory variable to define treatments, which are randomly assigned to experimental units or subjects, to then compare the responses of the different groups to the treatments received.
