Quantitative method

  1. 1. 1Main Question Post Wylie Tidwell 7/6/11 4:13 PM Comment [1]: 2- or 3-paragraph analysis of the relationships among tests and In a Quantitative Method, there are surveys and experiments. If a survey is selected it scales, populations, and reliability and validity. Additionally, post 1 or 2would provide the researcher with numerical values that could show a population’s opinions or paragraphs describing the test and scale examples from your discipline, including the populations, the reliability and validitytrends in regards to a particular topic (Creswell, 2003, p. 153). Whereas, an experiment will of each test, and whether the test and scale could be applied to another population.provide evidence of a possible outcome of a particular situation, within parameters set by theresearcher (Creswell, 2003, pp. 153-154). The relationships between test and scales, populations,and reliability and validly is essential for quality research. There are a few key reasons that we use test and scale in quantitative research. First, theyenable the researcher to represent various variables by a single score, which limits the hardshipsof dealing with complex data (Frankfort-Nachmias & Nachmias, 2008, p. 415). Next, the resultsgathered from scales and indexes are typically more accurate data (Frankfort-Nachmias &Nachmias, 2008, p. 415). Lastly, they increase the reliability of the measurement overall(Frankfort-Nachmias & Nachmias, 2008, p. 415). Remember, reliability is the errors that appearin the research due to inconsistently in the observations taken using a particular measurement(Frankfort-Nachmias & Nachmias, 2008, p. 154), thus helping with the empirical validity of theexperiment. For example, in Miles Maguire’s article, “Online Debates in Oshkosh: Using the Blog toPromote and Engaged Electorate”, the researcher used “a pair of experiments in using the blogformat as the mechanism for candidate debates” (Maguire, 2008, p. 327). The population for thisparticular research was the electorate and they way that media has affected the ways debates areviewed. The researcher states, “participatory journalism is a form of reporting that has beenenabled by the development of Web log software and that allows individual citizens –whethertrained as journalist or not –to take an active role in shaping the coverage of their communities
  2. 2. 2(Maguire, 2008, p. 329). The Likert scale used for the research asked how they would like Blogbased debates based on the population gender and age. The research was valid because theysurveyed the whole district and allowed answers to be “no response”. This type scale coulddefinitely be used within other populations because if using Internet based response systems, thisis the best way for it to be done.
