Response to 4 students postings with 60 words and 2 references for each response - Coursework Example The writer presents his findings from an approach whereby he looks at how and why both validity and reliability can be determined by using basic tests and scales. Moreover, the combination of more than one scale at a time is highlighted (OConnor, 2011). This was an important aspect for the writer to have covered because clears researcher who may have some doubts with introducing new forms of scales with an existing scale they may be dealing with from their doubts (Gardener, 2009). An important perspective of the writer’s work has to do with the fact that he stated off by taking more about the advantages of using scales. In this, he explains that scales are used to â€Å"resolve the complexity inherent in people’s behavior† (Frankfort-Nachmias and Nachmias, 2008, pp.422-424). By this, researchers get a first hand information as to the need for them to settle for one form of scale or the other. The writer could however elaborate more on the weaknesses of using specific scales so that researchers can be on the lookout for these weaknesses and address them appropriately in their research processes (Gardener, 2009, p. 232). Much of the focus on the measurement of the validity with the use of scales was narrowed to the population that the researcher has to deal with. In this, the writer emphasized that the population is the accessible group of people that the researcher would have to be dealing with (Experiment Resource, 2011). By this, other researchers are offered an insight into how well to manipulate their populations to ensure that they achieve reliability and validity for each kind of scale that they choose (Gardener, 2009, p.
