Experimental research Experimental research is commonly used in sciences such as sociology and psychology‚ physics‚ chemistry‚ biology and medicine etc. Experimental research tests a hypothesis and establishes causation by using independent and dependent variables in a controlled environment. KEY POINTS Experiments are generally the most precise studies and have the most conclusive power. They are particularly effective in supporting hypotheses about cause and effect relationships. However‚ since

THE LOGIC OF EXPERIMENTAL DESIGN The randomized comparative experiment is one of the most important ideas in statistics. It is designed to allow us to draw cause-and-effect conclusions. Be sure you understand the logic: • Randomization produces groups of subjects that should be similar in all respects before we apply the treatments. • Comparative design ensures that influences other than the experimental treatments operate equally on all groups. • Therefore‚ differences in the response variable

TRUE EXPERIMENTAL DESIGN DEFINED: This category of design includes more than one purposely created group‚ common measured outcome/s‚ and random assignment. It is regarded as the most accurate form of experimental approach. It proves or disproves a hypothesis mathematically‚ with statistical analysis. Criteria for an experimental design to fit as a true experimental design: The sample groups must be assigned randomly. There must be a viable control group. Only one variable

Experimental Research When we want to learn about the humans‚ we must experiment on the subject. There are current scientific and medical research that needs to be done on human‚ in this case there will be an experiment involving a clinical drug trial; a pharmaceutical company wants to test a new sleep aid. In order to learn more about the new sleep aid‚ researchers would need to study on patients who have trouble sleeping through the night. This can be the case of insomnia or it can be symptoms

To eliminate this extraneous sources of variation‚ a 5x5 Latin square design was used in which the Letters A-E represent 5 additives. The setting times‚ in hours‚ for the 25 molds are shown in the table: Table here: WORKER 1 2 3 4 5 1 D 10.7 E 10.3 B 11.2 A 10.9 C 10.5 2 E 11.0 C 10.5 D 12.0 B 11.5 A 10

The following article was published by Reuters and contains a serious methodological flaw. "WASHINGTON (Reuters) -- Brain scans show that the brains of people who are lying look very different from those of people who are telling the truth‚ U.S. researchers said on Monday. The study‚ using functional magnetic resonance imaging or fMRI‚ not only sheds light on what goes on when people lie but may also provide new technology for lie-detecting‚ the researchers said. "There may be unique areas
