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

HBS 2.2.3. Reaction Time Experimental Design I. Identify a Problem or Question: Can the reaction of an individual be affected by other external factors? II. Introduction: Reaction time refers to the amount of time it takes for a person to process and react to a stimulus. It is important in everyday activities‚ such as driving‚ and sports‚ but not much experiment is conducted to research on this matter. Reaction time with its practical implication can leads to great consequences‚e.g. d

* Advantages and Disadvantages of the Experimental Design Advantages: * As well as controlling the independent variable the experimenter attempts to eliminate unwanted extraneous variables. * Control over extraneous variables is usually greater than in other research methods. * Experimental design involves manipulating the independent variable to observe the effect on the dependent variable. This makes it possible to determine a cause and effect relationship. * Because of strict

Correlational Research “Correlation is a statistical technique that can show whether and how strongly pairs of variables are related” (Creative Research Systems‚ 2010). Correlation research method is used in scientific research to study the association and/or relationship between variables. When the association between two variables becomes correlation coefficient‚ it is being calculated through quantitative measure. The goal for using this method is to observe if one or more variables cause

Experimental Design Bio 1110 ! ! Background: Plants need water to survive. Water makes up 80-95% of the mass in plant tissues. Transpiration is the loss of water from plants in vapor form. 95% of the water is absorbed from the soil for transpiration and 5% is absorbed during photosynthesis for producing necessary carbohydrates for growth. The rate of transpiration is dependent on the amount of water in which is available within the plant‚ soil‚ and on sufficient energy to vaporize water

Since social anxiety is currently the third most recognized psychiatric disorder in this country (Muzina & Sayegh‚ 2014)‚ our team decided to conduct our research experiment on whether or not more adults were afflicted with this disorder in comparison to teenagers. We wanted to observe our subjects in a natural

as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the most accurate data on what effect fertilizer has on plant growth. Although many environmental factors could be tested‚ such as the amount of sunlight exposed to or the amount of water given‚ some of
