p PROSTATE CANCER

Stage 4 prostate cancer is in fact terminal , and number of weeks that a person could survive after detection is minimal

On the study that was conducted , at the first glance , it could show that the new medication is effective , thus prolonging lives of stage 4 prostate cancer patients . The mean number of weeks in the study is higher than normal . A 1 .2 weeks difference is indeed very vital in people 's lives

But if we are to look closely at the data given , it ranges from 3

to 45 weeks , and 45 weeks being the highest . Although 45 is the only figure higher that the mean (11 .02 , it has somewhat elevated the mean , and if we are to disregard 45 weeks , we would get 7 .6 as mean , lower than the normal mean . The last data (45 ) have significantly affected the mean and the standard deviation

If we are to compare the normal standard deviation to that of the study conducted , there is a 7 .82 difference , meaning in the study , more values fall outside the normal range . If we are to plot and compare to a bell graph (standard normal deviation ) the two means , one from the study and one from the normal patients , the bell graph is somewhat stretched showing huge difference and disparity of the two standard deviation

Being in the committee that would grant funds for this study , I suggest that we should extensively examine the results of the pilot study . We should look at the patient that has lived for 45 weeks after the detection of stage 4 cancer . We have to look closely if the project has indeed helped in prolonging his life or other factors have caused it like age , lifestyle , genetics , other treatment sought , etc . I believe that if we take that patient out of the picture , the study is not effective at all , therefore , not entitled for anymore grants
