Statistical Analysis of Experimental Data Research Paper

Statistical Analysis of Experimental Data - Research Paper Example Analysis of variance (t-tests) can be used to estimate the probability that the underlying phenomena are not the same (Sergey, &Valery, 2012). Research plays a major role in psychology. The results are relayed through statistics. In order to understand how people behave, think and feel, Psychologists depend on research. Research needs to be organized to be understood by psychologists; therefore statistics help organize the information and make the connection between the research and group of people for easier understanding. These professionals use statistical methods to help them make sense of the numbers they collect when conducting research (James, Glen, Robert, Reid, 1998) Psychology and other human sciences employ statistics in helping understand and in the process solve various issues. A common example can be seen with psychologists’ keen interest on how health is affected by stress. A focused question might involve the study of a specific psychological symptom and its im pact on the health of the population. To assess whether the symptom is a good indicator of stress we need to measure the symptom and stress levels in a sample of individuals from the population. It is not immediately clear how we should go about collecting this sample, i.e. how we should design the study (Mandel, 2012). The data sets that psychologists collect will usually consist of one more observations on one or more variables. A common example can be seen with psychologists’ keen interest.
