Pharmaceutical company has continued to invest in producing drug that would treat the positive and negative symptoms of schizophrenia without triggering its side effects. The company desires to determine which drug is more effective in treating mental disorder. This study aims…
This research method is appropriate in proving and rejecting hypothesis formulated by the researcher. Since this study uses statistics in determining the efficacy of the drugs, quantitative research is applicable through experiment. The researcher will select randomized group or patients that are diagnosed with schizophrenia. It also involves two groups: controlled and experimental so that the analysis will lead to the main objective of this study. Furthermore, quantitative research prevents biased result when properly used. It also allows for the repetition of experiment to reprove the result of the experiment.
To determine the effectiveness of drugs, the research utilizes the Clinical Global Impression (CGI) Scale that examines the patients’ status in terms of its behaviour, symptoms, and response to treatment. It documents the history of patients with mental disorders (Busner, 2007). According to Kadouri, Corruble, and Falissard (2007), the CGI scale is widely used in clinical research due to its “face validity and practicability.” Moreover, another metrics developed by Logothetis will be utilized because it involves “two receptors” that determine the function of drugs to the patient’s brain (Wood, 2011).
This study hypothesized that the new developed drugs is more effective than the previous drugs formulated by the pharmaceutical company on the schizophrenic patients. To collect the data, the researcher will select schizophrenic patients randomly. The controlled group will be given the previous anti-psychosis drug while the experimental group will be rendered the new drug produced. Each patient will take 7.5/30 mg of drug. Using the CGI Scale, the researcher will assess the effect of drugs on the patients. The CGI Scale consists of interviewing patients and recording their behavior or response to the drug used. Furthermore, the metrics is utilized to determine the effect of drugs on ...

Scientific research indicates that people with a deficiency in human growth hormone responsible to for the aging process suffers from overweight, lethargic, flabby and frail among other health problems. In this respect, researchers have argued that health problems associated with the aging process and in particular lack of enough human growth hormones in the body can be cured through the help of human growth hormone therapy.
The null hypothesis is stated to be true unless disapproved by the alternative hypothesis. Alternative hypothesis on the other hand is the hypothesis that there are random influences on the observation. Acceptance of the null hypothesis automatically leads to the
These hypotheses need substantiation or verification - or rejection - for one purpose or another. To this end, they gather data and allow them to support or cast doubt on their hypotheses. This process is termed hypothesis testing and is one of two main areas of
Statistical importance is found when it comes clear that the findings in the samples are likely not to occur if the findings are not present in the case population (Black, 1999).
Hypothesis testing divides into two categories: the null hypothesis and the
During hypothesis testing the researcher allows themselves a confidence level as they are not 100% sure of the event happening (John, 2007).
