What essential characteristics distinguish a true experiment from other research designs? What ethical problems do you see in conducting experiments with humans? “Experiments are studies involving intervention by the researcher beyond that required for measurement. The usual intervention is to manipulate some variable in a setting and observe how it affects the subjects being studied (e.g., people or physical entities).
The researcher manipulates the independent or explanatory variable and then observes whether the hypothesized dependent variable is affected by the intervention” (Cooper & Schindler, 2011, p. 208). The text also explains that in other forms of research the researcher has to accept things as they are, and in an experiment the researcher is able to manipulate the variables to see how things are changeable (Cooper & Schindler, 2011).
Ethical problems that I see that conducting research can have are possibility of the human having a bias towards the experiment, or the researcher influencing the person being experimented on. Another ethical problem could be confidentiality of both the researcher and the person being experimented on.
What is survey research? What are the advantages and disadvantages of using surveys to collect data? Describe a research situation where survey research is appropriate and explain why.
Survey research “is a measurement process used to collect information during a highly structured interview—sometimes with a human interviewer and other times without” ” (Cooper & Schindler, 2011, p. 242-243).
Some of the advantages of these surveys are they are relatively quick in conducting each survey and is less expensive than other forms of research.
Some of the disadvantages of these surveys are the error rate of both the researcher and the person being surveyed. Often times the person being surveyed may be in a hurry and not be completely honest when doing the survey. I know I have been guilty when I get a research company calling me continuously and just to get them to stop I have hurried through the survey not really paying attention to questions. Amazon’s Kindle® electronic book, magazine, and newspaper reader, has been more successful than its competitors.
The fact that the Kindle® reader was first introduced on the Oprah Show and was strongly endorsed by the host, Oprah Winfrey, may have contributed to its success. However, the original Kindle® reader has some physical problems, such as button replacement and page-turn speed. Correcting these problems resulted in a redesigned Kindle® reader, which was released in 2009 and received many positive reviews. What observation research might have been used in the redesign of the original Kindle® reader? How do you think the Researcher went about developing a process that would include Oprah in their Marketing Plans?
Opera is such a successful woman and so many people look up to her and watch her show. She is always doing things to give back to the community and as many people as she can. If Kindle was to give her so many free Kindle’s to give to her audience or even to third world countries she would endorse them. She would be able to get the word out and people are going to follow her. I know Kindle gives free online books away all the time. There is so much buzz about it on facebook and other social networking sites.
