The Experiment Resources Design - Assignment Example

Experiments, when used as research designs give more room for authenticating results, especially if the experiments are not conducted just once but several times.
2. Was there a correlation between the interventions and the results?

Indeed, the research showed a lot of correlation between the interventions that were put in place and the results that were manifested. It is not surprising therefore that the researcher remarked that “as expected, among the behavioral variables at program entry, there was a significant positive correlation among restrained, emotional and external eating” (Steinhardt and Bezner, 1999, pg. 7). It would be noted that given experiment based researches such as the one under study, researchers are always mindful about finding authenticating proofs to their hypothesis. Because of this, they always base their interventions on approaches that are related to the experiment such that the results must be a reflection of the interventions used. In the case of this study, it is seen that the researcher buffered the experiment, which was external eating with variables such as emotional reactions. This way, any results were likely to fall within the scope of one of the interventions.

3. Was this a longitudinal study?
Longitudinal studies look into the existence of given situations and concepts over a long period. There has often been confusion in thinking that longitudinal researches concern the conduct of research over long periods but that is erroneous. Longitudinal studies are judged by how long the situation has existed. Looking at the concept of weight gain and eating habits: and because the researchers made use of the emotional attitude of respondents over a certain period in their lives, it can be seen that this research is a longitudinal study.
4. The authors refer to this study as being “quasi-experimental.”

Why?
The judgment of a study is a quasi-experimental research study is based on one fundamental principle and that is whether or randomized method of data collection was used. In this direction, Trochim (2006) argues that “A quasi-experimental design looks a bit like an experimental design but lacks the key ingredient -- random assignment.” It would be seen that in the selection process used by the researchers, not much focus was given to the centralization of the selection process as a random selection process. Rather, the opportunity was given to employees to participate through written announcements (pg. 3). It is for the exclusion of the randomized nature of the experiment that the researchers referred to it as a quasi-experiment.

Part B: Finalize Planning
The finalized plan for my personally proposed research shall be based on experimentation. This choice is made amidst the several benefits that come with the use of experiments in research of this nature. It would be recalled that the fundamental aim of that research is to identify the possibility of identifying a piece of product through taste. The act of tasting is in itself highly practical and has a lot of testing strings attached that make it suitable for conducting very simple experiments. It is for this reason that the experimental research design shall be selected. Through the experiment, the hypothesis can better be proven and results can be judged as more empirical and valid.
