There were two key hypotheses in the research conducted by Newcomb, Sheier, & Bentler (1993). The hypotheses asserted that mental health problems are common among most drug users and drug use leads to other undesirable courses of actions such as suicide. Researchers collected information through sampling methods. Comparisons to other studies were also done. A sample of 487 participants was used. There were 136 men and 351 women used in the study. The age bracket for men was from 24 to 28 years while that of women was from 24 to 27 years. The study involved Hispanic, Blacks, Whites, Asians, and others. The results indicated that drugs contributed to 13.46% of mental health problems across all sexes. The research employed the use of inferential statistics, which base on the consistency of the reported mental cases among members of a given sample. The hypotheses of the study were supported to a little measure, because the results indicated that only 13.46% of the mental cases are caused by drug use. The inferential statistic was used in the study on drug and mental illnesses. Authors showed the appropriate statistic because the study was based on a sample of individuals in the entire community. The interpretation of the statistic was not correct because it was based on estimations from a smaller group of individuals. Another statistic would not be appropriate for the study because it only requires approximations from a large group of individuals. The key strength of the statistics it facilitates the determination of a given study using a small group of individuals from the entire population. However, the method is disadvantageous because it relies on approximations.

Britt (2007) conducted a research on the stigma of mental problems in the military using one hypothesis. The hypothesis asserted that most military individuals fear being tested of their mental problems. Both quantitative and qualitative research methods were incorporated into the study. The research involved 1000 soldiers who had returned from the war in Iraq. There were 700 male soldiers, while the number of female soldiers was 300. The results indicate that 15 to 17% of the troops returning from Iraq experienced stress, and 30% experienced mental problems. In addition, 50-60% of soldiers who could seek help relating to mental problems did not do so. The researcher used the inferential statistical method that is based on approximations. The sole hypothesis of the research is duly supported, because the ultimate results indicated that most of the soldiers were not willing to share their mental problems, in order to be accorded assistance. The used statistic was the inferential; it relies on estimations and approximations. The researcher used the appropriate statistic because of its efficiency in making approximations. The interpretation of the statistic was correct as is used in making approximations. Another statistic would not be appropriate because the research is based on sampling that is principally reliant on inferential statistics. The core strength of the statistic is that it is provided for approximations and assumptions basing on a sample. On the other hand, it is disadvantageous because it does not give the exact results of the study.
