provide evidence of a possible outcome of a particular situation, within parameters set by the
researcher (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, they
enable the researcher to represent various variables by a single score, which limits the hardships
of dealing with complex data (Frankfort-Nachmias & Nachmias, 2008, p. 415). Next, the results
gathered 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 appear
in 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 the
experiment.
For example, in Miles Maguire’s article, “Online Debates in Oshkosh: Using the Blog to
Promote and Engaged Electorate”, the researcher used “a pair of experiments in using the blog
format as the mechanism for candidate debates” (Maguire, 2008, p. 327). The population for this
particular research was the electorate and they way that media has affected the ways debates are
viewed. The researcher states, “participatory journalism is a form of reporting that has been
enabled by the development of Web log software and that allows individual citizens –whether
trained as journalist or not –to take an active role in shaping the coverage of their communities

(Maguire, 2008, p. 329). The Likert scale used for the research asked how they would like Blog
based debates based on the population gender and age. The research was valid because they
surveyed the whole district and allowed answers to be “no response”. This type scale could
definitely be used within other populations because if using Internet based response systems, this
is the best way for it to be done.
