experimental and quasiexperimental

  1. 0
    hi every body,
    I am a nursing student and I need a help with examples to understand what is making me frustrated..I have an exam on experimenatl and quasiexperimental designs...I understand that in the first one we use randomization and we must use a control group for comparison, and we dont use randomaization in quasiexperimental...may or may not have a control group.
    in which research studies can we use expweimental design?
    in which research studies can we use quasiexperimental design?

    thank you

    The way I keep them straight is to think of it terms of control. Absolute Control(s)=Experiment; Tight Controls=Quasiexperimental. True experiments usually are only done in the lab/animal research etc. where everything is controlled, such as food, water, temp, genetics etc. Quasiexperimental usually has tightly controlled variables/controls, but is usually done on humans. It would be highly frowned on to clone a bunch of humans, lock them in cages and then preform experiments on them, so instead we refer to experiments on humans as quasiexperimental.
