The presented case study determines the effect of workshops on spirituality. It established whether attending a workshop would increase one’s skills in dealing with spiritual issues. As such, counselors and social workers from western Michigan were invited to participate. The sample size included 30 workshop participants and a control group of 30. The sample size of 60 participants constitutes a large enough sample to represent councilors and social workers in western Michigan. The selected sample size assumes that the number of councilors and social workers is approximately 5% of the population. Thus, calculating for sample size (n), is the result of dividing the log of (ß) and log of (p). Log ß) is the probability of committing type II error which is 0.05. The proportion of councilors and social workers in the population denoted by (P) is an assumed 5% potion of the whole population. Therefore, sample size (n) translates to log0.05/log0.95 = 58 (Charan & Biswas, 2013) . Given that the sample size is large enough to cover the population of social workers and councilors in western Michigan, the results can be generalized to the entire population of western Michigan.
The generalizability of the result to Michigan in general, Northeast United States, and the United States as a whole is inaccurate. The study sample is specific in using social workers and councilors. However, the alternate hypothesis is not specific to a particular sample group in the population. As Wang et al. (2017) note, the specificity of the sample group limits its generalisability. As such, there is a chance of getting a different result when a different special group is used in the study. Thus, the results cannot be generalized to Michigan in general, Northeast United States, and the United States as a whole. However, if the study would have been changed to investigate the effect of attending a workshop on the skills of social workers and councilors in dealing with spiritual issues, the study would be generalized.
