In this experiment, mice are the object of study. Coffee and waterare the samples for the experiment and are supplied in equal ratios.Same duration of time is used in both groups so there is no bias. Themain objective is to determine whether coffee reduces chance ofdeveloping high blood sugar level thus reducing chances of diabetes.The method used is simple as a certain sample size is supplied withwater and the other with coffee and the results compared. It isevident from the results that there was no change in body weight forboth groups but the one supplied with water, blood glucose increasedsignificantly while that supplied with coffee the glucose leveldecrease by about 30% (Yamauch,2010). It is clear that coffee doesnot prevent development of high blood sugar levels. The control groupin this study which is the independent variable is mice supplied withwater while the treatment group is the mice supplied with coffee i.e.the depended variable.
To start with, it abundantly clear that the sample size wasextremely small. Eleven mice can be viewed as very few and cannottherefore be a perfect representative of the entire population.Additionally, there is no clear information on how the mice wereselected. Glucose levels of the mice ought to have been known priorto the experiment. Secondly, there are numerous potential bias insuch a study. It is evident that the coffee used in the experiment isa gift from a corporation. Without a second thought, one is bound tothink that such a corporation may have vested interests in theoutcome of the experiment. The corporation may want to portray thecoffee as extremely useful in maintaining people’s health henceincrease sales. In other words, commercial interests in the outcomeof the experiment may create potential bias.
The number of people suffering from diabetes today has increasedtremendously and this study seeks to find ways to control and treatthe disease. To me, this study brings into action efforts to researchmore on possible alternatives to use to prevent diabetes. This studymay also be helpful to me in that I can engage in extensive studyregarding diabetes or factors that may contribute to it.
