Introduction
The Scientific method is a framework followed by scientist in investigating a certain inquiry or process. Scientific method is a series of steps that was established during 1619 by Rene Descartes. This then led to the improvement of the principle so as being used until the recent times as a principle that guides every scientific fields (McLelland, n.d.). With scientific method, biases from personal prerogatives and the influence of environmental and social concerns are eradicated. The scientific method employs the utilization of testing procedures to verify claims that can be reproduced to strengthen the credibility. Scientific method is a flexible principle that contains a number of steps that are applicable to most of the fields of sciences. Hence, scientific method needs critical thinking that aids the goal to lessen uncertainties and get the most of accurate data and information (McLelland n.d.).
Discussion
Regarding the study about “New evidence that drinking coffee may reduce the risk of diabetes,” one of the observations of scientists that lead to this study is that drinking coffee decreases the possibilities of getting diabetes. Hence, the hypotheses were:
Null hypothesis: The intake of caffeine from coffee does not give a significant difference in the blood sugar level of the mice.
Alternative hypothesis: The intake of caffeine from coffee does have a significant decrease in the blood sugar level of the mice.
The experimental design used is the comparison of the blood glucose levels of the variable group and the control group. The variable group is composed of 10 mice subjected to diluted black coffee with ratio of 1:1 parts of coffee and water, while the control group is composed of 11 mice subjected to water only. The diet of both groups was monitored for five weeks and the monitoring of blood glucose were tested once every week (American Chemical Society, 2010). The independent variable in the experiment was the living condition of the mice while the dependent variable was the blood sugar level or concentration that depends on what fluid is to induced.
The results of the experiment showed that there is a significant difference between the control and variable group. For the blood sugar level of the control group, it increased to a significant extent when compared to the variable group that drank coffee. The variable group had 30% decrease in their blood sugar level as tested while the control group had an increasing blood sugar level (American Chemical Society, 2010).
After reading the articles, I inferred that there is a lack of information about the brand of coffee used, primarily focusing on the contents and ingredients. For example, the content of coffee, the ingredients and if there is some sugar added or was it pure black coffee. Nevertheless, the tests employed were good enough to get the results needed. Unfortunately, the sample size was not equal for both groups but there was no explanation given as to why this is so. I think it would be better if both samples would have had the same size. Bias could have been that the brand of coffee and the ingredients were not specified. The study was only limited to the testing of the blood sugar level that is based only on the intake of coffee or not. The diet of the mice was not specified clearly that could have affected the results.
Conclusion
This research is relevant in opening the possibilities for both people and products to reduce the risk of having diabetes. People can have the chance to enjoy their morning drink, black coffee, without the fear of having diabetes. However, it could have been better if the other positive and negative effects of drinking black coffee are included so as to make it a more powerful and relevant research when it comes to health. On the other note, for the product itself, the research can be a promotion strategy to make the economy of coffee rise.
