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).

An experiment can establish causation by manipulating variables and controlling for potential confounding factors, while an observational study can only show correlation. Experiments allow researchers to directly test hypotheses and determine the effects of specific interventions, providing stronger evidence for causal relationships. Additionally, experiments can help establish a cause-and-effect relationship with higher confidence due to their randomized controlled design.
An independent variable is the factor that is manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is thought to cause a change in the dependent variable.
The Tuskegee Experiment used an observational study design. Researchers observed the natural progression of untreated syphilis in African American men without their informed consent. This study was ethically and morally problematic due to the lack of informed consent and the withholding of treatment.
A control variable is a factor that is held constant in an experiment to prevent it from influencing the outcome. A control treatment, on the other hand, is a specific group or condition in an experiment that receives no experimental manipulation and is used as a baseline for comparison with the treatment groups.

Background research helps in the design of an experiment because it provides information that is already known about the experiment.

Well, you're going to need the right things and also you need to have experience if you are going to design an experiment.
