Using your research topic, design a laboratory experiment to test a hypothesis. You should describe your experimental design, commenting on each component of a true experiment. Specify clearly how the independent variable will be manipulated and how the dependent variable will be measured. While you are not going to actually conduct this experiment, this should be designed in a way that the study could be conducted by you.
Please note: an experiment is NOT a survey. For your experiment, you must recruit a sample, then *randomly* assign participants to the experimental group or control group, then manipulate an independent variable for the experimental group. It is not enough to let people self-select into the experimental or control group, and then compare the two groups. The fact that your independent variable must be able to be feasibly manipulated means that your independent variable should not be something like gender or smoking status (although you could design an experiment that manipulates how many cigarettes are consumed).
