Many millions of animals suffer and die every year in the name of science. How can this practice be justified? Public debate usually centers on the moral issues. (more…)
What is research? There are various definitions of research. According to John . W. Best, research is a systematic and objective analysis and recording of controlled observations that may lead to the development of generalizations, principles, theories and concepts, resulting in prediction for seeing and …
Abstract The research here has looked at the impact that cold water immersion has on the physical performance of athletes and the way in which this immersion can impact on fatigue. The results showed that cold water immersion has a direct impact on the level …
In the process of science, scientist use two main approaches to learn about nature; Discovery Science and Hypothesis based science. With Discovery Science, scientist observe and describe objects, and with Hypothesis based Science, scientist make a hypothesis, make deductions and then test the predictions. In …
Medical Experiments of the Holocaust Kaitlin Holocaust in History January 6, 2013 Many brutal atrocities were committed during the Holocaust by the Nazi party against anyone they viewed as “unpure”. This included the Jews, Gypsies, homosexuals, Afro-Germans, Slavs, communists, the handicapped, and the mentally disabled. …
We have discussed different learning theories (e. G. Classical conditioning and operant conditioning) in Lecture 3. Please derive ONE hypothesis related to any real-life issues based on one of these theories and then design an experiment to test your hypothesis. When you work on this …
The reappraisal of related literature is a indispensable facets of scientific research. Its entails the systematic designation, contemplation, critical analysis and coverage of bing information in relation to the job of involvement. The intent of reappraisal of literature is to obtain comprehensive cognition and in …
The lighting was kept constant during the complete test. No additional light sources were added throughout the experiment, nor were any light sources removed throughout the experiment. This minimized the errors involved with trying to read and record the indicated measurements on the ticker tape, …

Variable
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.
Hypothesis
The hypothesis is an educated guess as to what will happen during your experiment. The hypothesis is often written using the words "IF" and "THEN." For example, "If I do not study, then I will fail the test." The "if' and "then" statements reflect your independent and dependent variables.
Psychology
The experimental method involves manipulating one variable to determine if changes in one variable cause changes in another variable. This method relies on controlled methods, random assignment and the manipulation of variables to test a hypothesis.
Validity
Experimental validity refers to the manner in which variables that influence both the results of the research and the generalizability to the population at large. It is broken down into two groups: (1) Internal Validity and (2) External Validity.
