Installing a home theatre can be a dream come true. Home theatre design can range from the simple flat screen setup in your living room to an eight foot screen, 1080p movie projector, and 7.2 surround sound system. You can spend as little as $1,500 for a simple setup or as much as $40,000 on a fancy home theatre paradise.
Despite the obvious evils that Nazis inflicted on the world, behind closed doors doctors and scientists were conducting some of the most abhorrent and disturbing experiments on human subjects. According to NOVA, there were 30 such Nazi human experiments performed on concentration camp prisoners. The result was unimaginable pain, mutilation, disability and ultimately death. During the Nuremberg doctor trials, 15 of 23 defendants were found guilty of unthinkable war crimes.
By definition, all experiments involve manipulation of one or more independent variables, and observing the effect on some outcome (dependent variable). Experiments can be done in the field or in a laboratory. They can involve human or animal subjects. What distinguishes the type of experiment is the degree to which the experimenter can assign subjects to conditions. Three types are described here: True, Quasi- and Single-subject experiments. In a true experiment, subjects are randomly assigned to the treatment conditions (levels of the independent variable).
