Post theme 4

Quantitative methods as a concept should be easier to understand than any of the other themes so far. Who haven't done some kind of data collection through questionnaires and similar some time in school. While the concept itself wasn't anything new, I still found it interesting to see how it is applied in research studies. I will not pretend that I understand all the math used while calculating the connections nor have I looked at it closer, but it made me think about the importance of identifying as many parameters as possible before you perform your test that can affect the result both directly and indirectly.

Something I found interesting however during the lecture was how much work is put into refining the questions through qualitative methods to look for any weaknesses in your test. All the iterations of pilot tests where you try to avoid bias, confusion etc. with evaluations before you believe you have a good test that hopefully will give you usable data.

With this in mind, I don't think any study related to human behavior can be done effectively with quantitative methods alone, even though the data gathering is. I got some flashbacks to Kant and his quote “perception without conception is blind” thinking you can't draw any conclusions and understand your data unless you know what you want to achieve and that your test actually answer that question in a good way.

In the seminar we talked about some strengths of quantitative methods, and what came up is the fact that you can reach a high statistical significance without having to spend as much time and resources compared to if the data collection was qualitative, much like I discussed in my pre theme post. The most interesting thing, that I didn't think about before the seminar that seems obvious after hearing it is the fact that you might not be able to get any interesting information from a quantitative study. Ilias used the example of a study on homeless people where doing a qualitative study where the researcher lived with them for a time was way better to understand the environment they live in and take part of all what I like to call silent knowledge.


I also see a weakness in only using quantitative methods when attempting innovation in e.g. design work. I can't see any way you could use quantitative methods to make e.g. the study on tangible user interface in connection to learning children programming like in the paper for theme 5. Observation of the behaviour of the subjects in the study gave more information than any questionnaire could, and similarly any attempt to measure input data would miss all the important contextual information that might be of even more importance.

  1. You did a good job summarizing the main points we discussed during theme 4. It seems that you already knew something about the concept of quantitative methods but I like how it broadens your horizon when it comes to how careful you need to work with them. I like how you refer to Kant's quote "perception without conception is blind", because I also kept that in mind and thought about it again during last weeks theme. You gave a good example in your reflection how quantitative methods are not always the best way to analyze something. It points out how important it is to know the benefits and limitation of both quantitative and qualitative methods to design a good research.

  2. Hi,
    I think your idea of “refining the questions through qualitative methods” inspires me a lot on my own work in some degree.Actually,at the start of one project or test,I generally feel many limitations to enlarge our horizon and open our ideas,even can not pose a few questions.The more questions mean the more details we could handle in the beginning.From this perspective of view,I think it is optimal aspect from the lecture to my study.Thanks for sharing.

  3. Hi,
    Your reflection is great and it is good to see your thinking from a particular perspective other than the common popular ones. I could tell that you get involved with the study progress with a lot of personal thinking. You make a good argument on both quantitative and qualitative research. I agree with you that there are many scenarios in which the two methods are needed at the same time. Your examples are very useful and helpful to get a better understanding of the two methods. Well done. Thanks for sharing.
