RESULTS AND DISCUSSION 2Simulated Research Study # 1 Research study one used a quasi-research design and more specifically used a single group posttest-only design (Knight & Tetrault, 2017; Jackson, 2016). What makes this study a quasi-design is because the researchers used a convenience sample as their population, meaning the participants were not randomly assigned. According to Knight and Tetrault (2017), quasi-designs are best used when researchers cannot obtain sample participants that can be randomized. In order to make sure the experiment is “true”, implementing a quasi-design can help researchers obtain the “gold standard” in their experiment (Knight & Tetrault, 2017). Additionally, because only one measuring instrument is used in this study, a more specific designunder the quasi umbrella is the single group posttest-only design (Jackson, 2016). Because the study is only testing one group, a single group design is necessary. Jackson (2016) further reveals that a quasi-design or a single group posttest-only design is best when a study is not really manipulating or controlling paricticular variables. In this case, the researchers of this study are not really controlling their groups, rather, they are simply investigating if there is any kind of difference between them. Participants come to the experiment with or without the characteristics under investigation. Lastly, this specific design accurately tests the null hypothesis that there will be no significance between substance abuse users and the general population and their emotional understanding. The statistical test used for this study (single sample t-test) was the correct choice. According to Knight and Tetrault (2017), a single sample t-test is utilized when researchers are comparing one group to a general population. In regard to this study, the researchers are wanting to see if there is a difference or any comparison between one group and the population rather than a relationship. If the researchers wanted to investigate a relationship between the groups
RESULTS AND DISCUSSION 3(ie. does a specific treatment affect emotional understanding in drug abusers?), then a t-test for correlated groups would be more appropriate (Knight & Tetrault, 2017). According to the SPSS output for this research study, the results were significant. P equaled exactly .000, meaning that it was less than 0.05, therefore significance was found. The researchers can then reject the null hypothesis and report that the data is in favor of the alternative hypothesis (Knight & Tetrault, 2017). Lastly, the implications with this study was that the sample size of 40 participants was a bit large for a single sample t-test (Knight & Tetrault, 2017). Knight and Tetrault (2017) argue that a sample size less than 30 is appropriate for this statistical test, however, it is a general number to abide by when selecting tests to analyzedata.
