I prepared myself for the theme by reading all the
material on the weekend before the pre-theme deadline. By doing so I had time
to reflect and try to make sense of the thoughts that arose. To be able to
answer all questions, I googled for additional background information. From
IEEE MultiMedia volume 22, I choose the paper “A Survey of Current YouTube
Video Characteristics” published by Xianhui Che in 2015. The paper studies
YouTube videos to better understand their characteristics and to demonstrate
consistency with previous research. In addition to this, the paper also
presents new categories of features emerging. Due to Google's acquisition of
YouTube in 2007, there has been some changes in user policy and service
infrastructure. The choosen paper has an impact factor of 1.694. Furthermore,
we should read “Drumming in Immersive Virtual Reality: The Body Shapes he Way
We Play” written by Konstantina Kilteni, Ilias Bergstrom, and Mel Slater which
focuses on body ownership illusion.
As an introduction to the lecture, we defined
quantitative research methods. Since they are depending on numerical
measurements, they may come from whether asking participants directly using
questionnaires or observation under uncontrolled conditions. After collecting
the numbers, we interpret the results with the help of statistics. Regarding
the questionnaire, we figured out that their use varies between disciplines. In
experimental psychology, before a questionnaire is considered ”valid”, it goes
through numerous tests and experiments, designed to ensure that it does indeed
answer the question that it was designed to answer. Therefore, researchers use
established questionnaires which have been tried and tested. Nevertheless,
sometimes researchers create their own questionnaires.
Furthermore, we focused on hypothesis. A hypothesis is
proposed for the statistical relationship between data sets. This is compared as an alternative to a null
hypothesis, of no relationship between the data sets. The comparison is
statistically significant, if the relationship would be an unlikely realization
of the null hypothesis according to a threshold probability - the significance
level. Hypothesis tests are used to
determine what outcomes of a study would lead to a rejection of the null
hypothesis for a pre-specified level of significance.
One of the most interesting parts of the lecture to me
was the part about the body ownership illusions. The hypothesis is that the
avatar which is considered more appropriate culturally, will cause participants
to exhibit a more complex movement pattern. According to my approach in the
first blog post, full body ownership illusions can lead to substantial
behavioural changes in the context of musical performativity, depending on the
appearance of the body.
In the seminar, we discussed in small groups different
aspects of the lecture starting with the advantages and disadvantages of
quantitative research. As an advantage we mentioned that the results are
representative and it is easy/cheap to collect data. Furthermore, quantitative
research data is generalized and because of that reliable. I could contribute
in the discussion with my findings from the first blog, e.g. the disadvantage
of using quantitative methods is that the cause of a finding or an attitude
such as dissatisfaction is not determined. You do not get a deeper
understanding. In the discussion in class, we also mentioned that quantitative
research methods allow to apply the same metric on different people. In
addition to this, we discussed that an experiment is always designed and that
qualitative and quantitative research methods could be objective and subjective
at the same time.
To me this theme was quit helpful since I did not have
any courses focusing on quantitative research methods in my bachelor’s studies.
It seems that you put a lot of effort in understanding this theme and I like how you structure your reflection due to what you have done and what you learnt during the lecture and the seminar. You also show that you linked former themes to this weeks, which is probably the main goal of this course. I think you need to be careful when you say that quantitative research data is generalized and because of that reliable. For me the most important thing why a study can be reliable is because you can repeat the study and still get the same results. Therefore you need to have a good design of your method and preferable a very objective way of dealing with data. I like that you learned so much about quantitative and qualitative methods in this theme even you did not have that much knowledge about all that before.
AntwortenLöschenHi! You did really great reflection, it's very well structured and summarized. I found a lot of new information for me in your post. I like your statement that hypothesis is proposed for the statistical relationship between data sets. You defined benefits and disadvantages of qualitative and quantitative methods very clear. It seems that you really know that topic. Well done!
AntwortenLöschenIt shows that you have really understood this week’s theme. Your posts are very well written, thought through and interesting to read. Your reflection of the week helped me summarize and understand the most important aspects of this week’s theme and you gave examples which explained your thoughts and comments in a clear way. We were in the same seminar but I agree with you in your discussion and think that an interesting aspect was the objectivity discussion. Keep up the good work!
AntwortenLöschenHi Corinna,
AntwortenLöschenThank you for another good blog post of reflections! I would like to say that the part about the hypothesis was really interesting, especially that reasoning of the significance level which I learned about now when I read your blog post. I also think that you describes the differences and benefits/limitations between quantitative and qualitative in a good way, for example that quantitative methods are depending on numerical measurements, easy and understandable text, good job!
Hi!
AntwortenLöschenThanks for interesting reading and a well written blog posts. It shows that you have made a solid preparatory work and that you have read the literature in advance so you can answer the questions of the theme. I agree with you that one of the most interesting parts of this week's theme was about body ownership illusions, which really got me redefining how we think about virtuality. Well done!
