QUANTITATIVE REASONINGThe research need involving the experimental treatment of 12 prostatic crabmeat patients clinically diagnosed at stage 4 showed that the entertain livelihood span after treatment was 10 .75 , with a standard deviation of 11 .02 It is known that the close tone span of untreated prostate cancer patients at the same clinical stage 4 is 9 .6 , with a standard deviation of 3 .2 . The difference in life span between the experimental and the control assemblys is not square(a) enough to convince the committee that the novel treatment for prostate cancer is effective enough for further testing . In addition , the standard deviation derived from the experimental assort indicates that the distribution of the life spans of these 12 patients were scattered along a elementary range , unlike that of the untre ated or control gathering , which shows a smaller standard deviation value of 3 .2 .
The lower standard deviation value of the control group is more reliable because it reflects that there are little differences in the life span of the patients in this groupThe size of the mull hunt down is also questionable because only 12 prostate cancer patients were included in the study . If the research study is lowly to be an experimental treatment or clinical tryout , it would be more convincing if a big study population were involved in the investigation . A bigger study group would eliminate chances of bias and would also be resistant to outliers or valu! es that are extremely rise or low .
