Experimental research is essential for uncovering facts about medicine, basic science and other fields, but sloppiness can cause problems. In addition, some experiments can be dangerous for participants. Ethics plays a significant role in experimental research.Know More
Experimental research involves testing hypotheses to determine if they match the evidence. One of the most difficult parts of performing experimental research is eliminating confounding factors. While research tends to be slow, it is essential for testing physics hypotheses, determining if specific medical treatments are effective and testing a variety of equipment.
However, studies have shown that a significant portion of experimental research is tainted by improper methodology, bias and poor statistical analysis. Small mistakes committed by the researchers can cause experiments to show significant effects when none exist, and some scientists have even made up results in the past.
Experimental results must be replicated for them to be accepted, and peer-reviewed publication is essential for finding any problems that existed in the methodology researchers used. In addition, many experts are calling for more sophisticated statistical analysis. While problems are common, experimental research has led to longer lifespans, improved health and a broad base of basic scientific knowledge that has led to countless inventions.Learn more about Social Sciences
During participant observation, which is used in social science studies, the researchers actively become part of the group being investigated. This first-hand, embedded method of collecting information often leads to copious, rich data. However, researchers have opportunities to interfere with the process, and this has the potential to skew results.Full Answer >
Purposive samples target a very specific population, which can help gain detailed insight on their characteristics, but a disadvantage is the difficulty in reaching a large sample size. Defining the target for purposive samples can be difficult, as all targets may not be known.Full Answer >
DNA profiling has the advantages of helping identify potential genetic diseases and helping law enforcement officers identify criminals. Disadvantages of DNA profiling include the possibility for error and the potential for the information to be used for nefarious purposes.Full Answer >
Censorship is the control of information through the suppression of media outlets, including books, television, news publications and other media of information. Perceived advantages are subjective and can range from political control to the reinforcement of religious values and ideals. Disadvantages include violations of individual rights, limiting education and restricting business growth, according to Ashley Poland of Chron. What one sees as an advantage, another may see as a disadvantage.Full Answer >
