This is essentially a closed loop process as shown in figure 2. If the objective is not met‚ the procedure must begin again with modified parameters.

3. Develop a detailed training evaluation strategy that Tom can present to Cathy which would provide evidence of the effectiveness of a particular training technique. First‚ the evaluator must be concerned with the general principles of experimental design. There must be enough control in the evaluation process to be able to decide at the training program. We must be able to answer the following four questions: a) Did change occur? b) Is the change due to the training? c) Is the change related

RCT are the most strict kind of research design.

Case Study A case study is an in-depth study of one subject/participant or a small group of subjects/participants‚ often carried out over an extended period of time (longitudinally). Within the case study method a number of different data-gathering techniques can be used. For example‚ recorded interviews‚ case notes (of therapeutic interviews‚ for example)‚ observation‚ as in the ape language study‚ and psychometric tests‚ which come up in the study The Three Faces of Eve. The strengths of the

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

Reports of research that employs single case experimental procedures do present the results from several subjects and often in several settings. The tradition in single

The sample of the study included 150 procedures in the control group and 91 procedures in the experimental group from the ages 0 to 17 years. The primary aim of the study was to increase the first-attempt success rate of venipuncture and decrease procedure time for the study population.
