Select a media technology research paper that you argue is
using quantitative methods in a good way. The paper should be of high quality.
1.
Which quantitative method or methods are used in the paper? Which are
the benefits and limitations of using these methods?
2.
What did you learn about quantitative methods from reading the paper?
3.
Which are the main methodological problems of the study? How could the use
of the quantitative method or methods have been improved?
The paper I choose in this theme is Internet
and Social Media Use as a Resource Among Homeless Youth, this is an exploration research to investigate
how does the internet and social media used in those homeless youth, thus for
that to find out and understanding how homeless youth use media networks
bridging social capital and maintained social capital. The finding in this
article will also be a resource to help those group.
This research collecting data from a convenience sample of 194 homeless
youth with the age is 13 to 24 for who used the internet before by using a quantitative method which is an internet questionnaire, for those
subjects answering their self-information and use internet for what purposes. The benefits for that is make the
results within an explicit form that can easily and clearly to see the findings
and helpful for analyze. However, limitations
also expressed for this method, cause the data in this research are
self-reports so maybe the youth cannot represent their actual use of the
internet. The data are drawn from a convenience sample, have a risk for biases
in it. They are not collect data on the media literacy or media competence of
subjects, they could not say if the youth really now that how to use the network
to get what they need. They did not have detailed data considering special
types they researched. Those all are problems easily appeared by using this
method.
I think the method the author used in this research is very suitable, a
questionnaire can extensively and effectively collecting data in a short time.
By designing the questions can control the direction we want to know. The statistical
method can give an intuitive result make the researchers easier to find things
they expected. For example in this article, the author give the question that
what does the youth use the internet to do, he collect data and statistical
results via a table form to show them, then we can easily find that homeless
youth are more likely to use e-mail when connecting with others. Thus we
analyze that they just try to hide their homelessness, then we think about how
should we find a good way to help those youth without damage their hearts.
I am not sure what is the main
methodological problems in this article or in other words, I am not sure
the means of it. In my opinions, they want to investigate how does the homeless
youth use the internet and media to do, they give their hypothesis and test it
with a questionnaire, and then discussion the result. However, we should
considering more details when using a questionnaire to make results more
representative.

Read the following
paper written by Ilias Bergström and colleagues. Reflect on the key points and
what you learnt by reading the text.
This paper suggest that a virtual body can substitutes the
person’s real body in the visual term. There have 36 subjects be tested in a
between-groups in IVR and represented with two models CD and FL in the
experiment, the results shows that the subject feeling the virtual body in a
virtual environment likes the real body themselves. This paper is very
interesting cause I am very interested in virtual reality. But I have some
questions that how does the author definition the two type CD and FL in this
research, what will happened if use a yellow color skin? However, this research
have a huge development prospects can extend to many fields and can be widely
used and served for human society.
1. Which are the benefits and limitations of using quantitative methods?
Quantitative methods is the use of statistics,
mathematical or computational techniques and other methods to carry out
systematic empirical study of social phenomena.
The benefits
of quantitative methods:
Quantitative methods have more reliable and
objective, it can use statistics to generalize results, users can easily change
relationships between variables and can establish cause and effect in highly
controlled circumstances, thus can reduce and restructure a complex problem.
Limitation:
Quantitative method does not study things in a
natural setting, the main limitation is that a large sample should be studied
in order to ensure the correctness and completeness. The larger the sample of
subjects researched, the more statistically accurate the results will be.
2. Which are the benefits and limitations of using qualitative methods?
Qualitative method is “a method of inquiry employed in many different academic disciplines,
traditionally in the social sciences, but also in market research by the business sector and futher contexts including research and service demostrations by the non-profit sectors".
Benefits:
Qualitative
method does not need a strict design plan before a research start, this make
the research more freedom and unfold naturally. The researcher can get more
detailed and rich data in a written descriptions or evidence.
Limitations:
It
will easily gain biased view in the research and will heavily skewed data
gathered. It also need to consume more time into it.
