What are some experiments for a experimental control group?

What are some experiments I can make up?|||Hi :0,


In traditional lab experimental design we pick a topic of interest that may answer a question or test an hypothesis. While there are numerous variations, a simple example would be to select a sample from a population of interest... sort members of the sample into a treatment group and a control group using a random technique such as a coin toss... then expose the treatment group to the experimental variable while avoiding such exposure to the control group. We'd then measure the effect we're interested in for each group.. experimental and control. Any difference beyond chance would be associated with an experimental effect.





Example: Walk up behind someone [experimental group subject] and clap your hands [independent variable]. Watch to see if they exhibit a startle reflex [dependent variable]. Do this for each member of your experimental group. Record how often you get a startle reflex. Then walk up behind someone [control group subject] but don't clap your hands. Record how often you get a startle reflex. Do this for each member of the control group. Compare the mean score [average] number of startle reflexes between the experimental group and the control group. See if the clap of hands is associated [correlated] with the startle reflex. Notice that the purpose of the control group is to have something to compare to the experimental [treatment] group. Regards.
