What is 2 condition experiment design?

A two conditions experimental design presupposes that you will have two samples, most often one receiving some sort of intervention or treatment, and the other being a control group. For example, group A could receiveda medication aimed at reducing symptoms of depression, whereas group A would receive a placebo, allowing for comparison of the two groups and ultimately finding whether the drug had a significant effect. Another example would be showing sample A a video filled with images from the media depicting women as thin, gorgeous, etc. and show group B normal everyday life ads. Exposition would be followed by a questionnaire about body image to see whether the media influence self image. As such, an experimental design will also often include a series of testing. Thus, there will be testing prior to exposition to treatment or intervention (pre-test), the intervention itself, and then another set of testing (post-test).
