Theme 4: Quantitative Research

I chose the article Making sense of multitasking: The role of Facebook, by Terry Judd (2013) and it was published in the journal Computers & Education with an Impact Factor of 2.775. The article investigates the impact Facebook has on university students’ general behavior when it comes to multitasking and focused behavior. They hypothesize that Facebook is associated with an increased occurrence of multitasking, that it initiates and maintains multitasking behavior, and that Facebook users are generally more likely to multitask.


The quantitative methods of Making sense of multitasking: The role of Facebook

I believe the article make use of pretty much straightforward quantitative methods for its study. The study takes place at an Australian university where it collects detailed data-logs of students’ computer-based activities in an open-access computer laboratory. They then separate the different activities performed, give them task names (i.e. Facebook, Google search, Microsoft Word, etc.) and count how many tasks were performed at the same time and how often the subject was switching task, during a session and during segments with specific time intervals. Depending on the count, the study defines the session as focused, sequential or multitasking. Over all the study makes use of 3372 collected sessions from 1249 different students.

Since the study did use a fairly large group of people and many recorded many sessions that were quite accurate, it could obtain solid results, where the evidence supporting the three hypotheses in general was reasonably strong. The method is efficient – data was collected rather smoothly and results were easily processed and gave clear results.

There are however limitations to the method. The results only represent the data collected from students at a certain university, in a certain country, during a certain time, etc. The study does not represent the whole world, or even every computer/Facebook user. There is also no exact definition as to what is considered to be multitasking, which in a sense makes the results vague. This type of method is also making predictions – it does not explain why or how Facebook would induce multitasking, it only suggests that it does. Perhaps with the use of more intricate interviews with the subjects, or another form of qualitative data gathering, the study could render a deeper understanding of the subject.


The quantitative methods of Physical activity, stress, and self-reported upper respiratory tract infection

The purpose of this study is to examine the relationship that exists between physical activity, stress and self-reported upper respiratory tract infection (URTI). The study examines this relationship by Web-based questionnaires to assess disease status, general lifestyle, physical activity and perceived levels of stress of 1509 Swedish men and women that had reported URTI. The conclusions they could make from the study was that high levels of physical activity might reduce the risk of URTI, and that highly stressed people may benefit even more from the physical activity.

Which are the benefits and limitations of using quantitative methods?

As mentioned above, when analyzing the method of the previous paper (which is somewhat similar in its methods), quantitative methods can be very efficient when gathering data, analyzing it and processing the results. In general the quantitative methods offer a way to gather and process a larger quantity of data. However, the data gathered will not necessarily provide significantly deep insights into how and why a phenomenon occurs. The quantitative methods are generally used in the social sciences, and generally make use of statistics.

Which are the benefits and limitations of using qualitative methods?

As opposed to the quantitative methods, the qualitative methods will provide deeper insight – they examine how and why the phenomena occur. The quantitative methods can consist of interviews, historical research and such. It can also provide an understanding of the conclusions made by the quantitative methods.

Qualitative research is however limited in the sense that it might be harder to analyze the data, detect the necessary patterns or extrude the significance for the study in question. When using qualitative methods it is also generally harder to obtain large amounts of data. The method might, for instance, be more time-consuming, harder to preform or harder to generalize to fit the circumstances.

  1. Hey.
    Interesting choice of paper. I think many computer users multitask, that's usually the case. You argued that they didn't explain though why or how Facebook would induce multitasking. I agree that there should be an explanation to his suggestion. But I think the authors might have thought that's the case because of the reason that people on Facebook link stuff to each other, chat, message and comment. So kind of naturally it would induce multitasking? Clicking on the links brings you to that website and while messaging or commenting, you may go do something else while waiting for a reply. I think that's the case for pretty much every social platform and not exclusively only on Facebook? That'd be my guess. However as you wrote, the authors would be able to support their suggestion with qualitative data gathering, which they could have done after the students' computer tasks.

  2. Hello Johan!

    Well written post, but I do however have some questions. You talk about the limitations of quantitative data, both because they only include one single university in one country and that they don't go deep enough in their research. This is valid concerns and I agree with you. But when is it satisfying to just have the quantitative data? Shouldn't all papers strive to get more depth?
