Essay 1
In an experimental research, the use of a research question answers the thesis statement that enables one to research about a problem (Yin, 2013). From the experiment, the research question can be clearly stated as “which vaccine is more effective for preventing getting the flu”. In this case, the problem being researched about is the flu the possible solutions to this problem which the use of vaccines is being analyzed. The null hypothesis of this experiment states that there is no effective vaccine for preventing getting the flu while the alternative hypothesis states that there is an effective vaccine for preventing getting the flu. The results obtained from such an experiment should be significant in that they should not be those that purely occur by chance but they have other causes for their occurrence. From the experiment, the results obtained are statistically significant because only a large proportion of the entire population of 1000 attempts to agree with the alternate hypothesis and therefore the null hypothesis would be rejected by the researchers.
However, the results from this experiment provides a clear view that 420 out of 500 participants were prevented from the flu by use of the shot and 380 out 500 participants were prevented from the flu by use of nasal spray. This shows that the most effective vaccine for preventing flu is the shot. It therefore gives sufficient evidence to support the alternate hypothesis that there is an effective vaccine for preventing getting flu. A sample of 500 participants in both researches is appropriate for this study since provides a wide area of study to the researcher hence enabling him to obtain almost accurate results in his research. However, the study might have had certain limitations like lack of enough research materials to reach the large population, insufficient funds to contact the study and
