Hey Guys,
Got a question, its probably but I just want to make sure:D
What are two features that best distinguish an experiment from other research methods?

Thanks Heaps 

[totaled]

other research methods as in what?

an experiment is primarily focused around investigating a cause-effect relationship (i think it's important to highlight tihs whenever anything is asked about defining/explaining WHAT an experiment is)

[Ravit]

That was the wording of the question, but the question wants you to compare the factors that are unique to experiments with respect to others research methods- surveys, observational studies, etc.

Two main features of an experiment:

- There's an independent variable that participants may be randomly assigned to, along with an operationalised dependent variable.

- It tests a hypothesis under controlled conditions with both an experimental and control group present.

Also totaled makes a good point, discussing the cause-effect relationship is another valid answer
