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

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

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

* 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

There are several techniques used in Experimental Research and are broken down into several methods of research used in psychology. These research methods are Naturalistic Observation‚ Correlational Method‚ Experimental Method‚ Clinical Method and Survey Method. The Experimental Method is used to give the researcher more control over the experiment. This is the most scientific method of research because the researcher is able to deliberately manipulate the IV (independent variable) while controlling

Research Question Investigate the effect of temperature on the rate of respiration of various parts of plants (germinating seeds and dormant (non-germinating) seeds)‚ by measuring the oxygen consumption and change in gas volume of respirometers containing either germinating or non-germinating seeds at different temperatures to measure the rate of respiration of these beans at different temperatures. Hypothesis 1.Germinating seeds have a higher rate of respiration as compared to non-germinating

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
