Question

I need to know what type(s) of research method this study used. In the study, participants were asked questions before and after receiving a treatment. The catch is that this study had no control group, so the results were gathered from comparing participants feelings before and after the treatment. Would this make the research methods of this study an experiment and a survey?

Answer 1

An experiment needs a control group.

Answer 2

So what research method did this study use? They have an Independent and Dependent variable and participants received treatments, so I think this is an experiment. I didn't design the study, I just need to analyze it for a paper. Thanks.
