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
Atomic energy, also referred to as nuclear energy, is used to generate electricity, and has applications in the fields of agriculture, medicine, research and industry, too. Atomic energy contains highly active radioisotopes, which are various forms of atoms comprised of the same chemical elements. These isotopes share many chemical properties, but have different volumes of relative atomic masses, which makes them suitable for different chemical, electrical, engineering and industrial practices.Full Answer >
Chemistry provides several key advantages to the public and the fields of medicine by allowing for basic needs to be met and allowing for the production of medicines. Chemistry, indirectly and directly, provides benefits for people around the world on a daily basis. It helps meet basic needs such as clothing, energy and shelter, and contributes to the improvement of air, water and soil quality.Full Answer >
There are many benefits of stem cell research for medicine and science, and the disadvantages are often social or cultural in nature. A number of groups are against stem cell research for ethical or religious reasons, especially when the research involves embryonic stem cells. Scientists believe stem cell research will lead to regenerative discoveries that could treat or cure diseases such as cancer.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 >
