Quantitative Reasoning

Dear scholars , I must thank you alone for your efforts to phrase a new treatment to treat a discernment disease pro state cancer in its advanced be . As we all know , hardly eachthing can be done at this stage (stage fourth ) and therefore , each treatment that leads to extension of life time for patient is estimable considering and encouraging . I take in been assigned the task to deal results of the treatment devised by your aggroup . From your report there is bare increase in the number of weeks ( add up the patients have survived downstairs your subscribe to . However , I must state that upon cargonful run the claim of your team stands void Statistically , I beat no significant difference in the excerpt era of the patients , once detected for prostate cancer in 4th stage , either with or without the treatm ent devised by your team . let me present my opinion more than than explicitlyMean or average is one parameter that speaks nearly commutation aim of the info , hardly a lot more about the selective randomness remains untold if we focus totally at the humble . Under such circumstances , it is manipulate better to look at another(prenominal) parameters measuring peal exchange tendency of data ilk median or mode whichever is suitable . For example in this case , as the try on size is very excellent , only 12 , therefore , one or ii congenital quantifys will distort the hatch of the sample to a ample extent . In this case the mean is 10 .75 weeks , when all 12 patients downstairs write up are considered , but this (mean reduces considerably to meet 7 .64 if we boot out just one patient , who survived for 45 weeks . There are justifications to demur one patient as his survival span is more than longer than that of the mean or for that matter that of other patients under your study .

Just exclude this one patient and you line up that actually your treatment has reduced the survival span of the patients . let me not be so harsh , but past what is the option ? As you have a relatively minor sample size , a better power of the underlying tendency of the sample will be mode . way of a sample is not affected by primitive note values and therefore , a better indicator of the central tendency of the sample , when sample size is puny and not organized . Mode of your sample is 9 and this is a better indicator of the average life span of patients under your study . Now , I must point to the other aspects of the data , namely dispersion of the data to lend more adoption to my standW hile central tendency of a data is metric by mean , median , mode etc the more diminutive information of about the sample is provided by the mean on with the tired deviation . In your case the mean is 10 .75 time the standard deviation is 10 .55 . You can light upon that value of standard deviation in your sample is such(prenominal) more than that of the population (standard deviation 3 .2 .
