True Experimental Design: Medicine for Headache Essay Example
The designated classification of design encompasses multiple intentionally formed groups, consistent measurements, and random assignment. It is considered the most precise form of experimental methodology. This approach utilizes statistical analysis to mathematically prove or disprove a hypothesis. To fulfill the requirements of a true experimental design, the sample groups must be randomly assigned, a viable control group must exist, and only one variable can be manipulated and tested.
The subjects undergoing testing need to be randomly allocated to control or experimental groups. With a true experimental design, the results can be statistically analyzed, leaving little room for disagreement. The exp
...eriment can be easily replicated to confirm the findings, and manipulation of a single variable is simpler. Typically, this design provides a definitive answer, either yes or no.
A study was conducted to assess the impact of a new headache medication on 80 subjects. The participants were randomly assigned to two groups: one group received a sugar pill while the other group received the new medication. Both groups underwent treatment for 3 weeks. Following this, a t-test was performed by the researchers and they examined the p value, which revealed a significant distinction between the two groups with a result of .03. Consequently, it can be concluded that the new headache medication is efficient in alleviating headaches.
