Essay on sociology research methods- experimental method !

Hi all,

Wonder if anyone can help me with my essay on sociology research methods !
Here is the essay's topic:
"Only the experimental method can give causation". Consider the truth of this statement and also consider the value of the experimental method in understanding the effects of mediated violence.

Any help will be very much appreciated :-)
Thanks ,

This is a tough topic, because it requires you to write about the other types of design as well.

If I use a case study design, can I make conclusions about causation? Or can I only observe?
What if I use correlational research?
Can you find any articles about causal comparative research?

What about ethnographic and survey research? I argue that ethnographic work and survey work can only provide data about how things are and cannot tell us about causation.

You should write a paragraph about each kind of research design and show how it can or cannot show causation. I think an experiment might indeed be the only way to show causation.
