I am currently writing my master's thesis, but I have a sneaking suspicion that it will not be very good. This is partly because I have been unable to test the system I propose in the thesis properly, because testing it involves test cases that has to be manually performed, and I simply haven't got the time/resources/mental sanity to do more than a handful of them.

The problem is that having little testing could be viewed as a large, weak point in my thesis, and is easily attackable when I shall defend it. My thesis is about detecting malware that requires human interaction (hence the testing difficulty), and by looking at some indicators I can determine what is malware and what is not. But my fear is that these results won't be very generalizable because of the small sample size. So my question is then: can a master thesis still be good if the presented results only cover a laughably small sample size?

  • Aaaand if someone were wondering, my master's thesis did actually turn out very well, and I got a nice grade. :-) It seems that the sample size was not an issue after all. Commented Jul 20, 2015 at 19:43

My Masters project (synthetic chemistry) didn't actually generate results other than failure and black goop (so nothing novel!) until the last two weeks of time I had in the lab, and even then, there was insufficient purity and quantity of my compound to do a complete 'standard' panel of analysis. It was the 4th year of an integrated BSc/Msci course, was graded including a viva and I achieved a mid 2.1.

The main purpose of a research Masters, at least in chemistry, is to accustom you to 'proper' research methods, while allowing you to pursue something novel and to demonstrate your ability to conduct research to a sufficient standard. In my cohort there was typically a tradeoff between novelty of project and quality of results, where one forgave the lack of the other.

As long as your thesis is written with an awareness of its deficits (aims far loftier/broader than the time/resources available sounds like a good start!) and you write good further work and conclusion sections where you tie this awareness in, making sensible conclusions and observations on the few cases you have achieved, I think it is definitely possible to write a good one! As Paul indicated above, you should discuss these concerns with your supervisor and possibly head of class (or equivalent). I am sure they will have dealt with someone with your concerns and circumstances before.

  • Usually, there is not enough time during a Master to do a full proper analysis. You should prove that you are capable of doing the work, and show that you know the problems and how to overcome them. Consider that in many cases, a master's project is used by the supervisor to check if there is potential for a PhD, where it would be done properly.

Good enough to publish your results: Most likely no. Unless low sample sizes are typical of the research papers in the same field trying to collect similar data, you can't expect lack of results to be publishable.

Good enough to still pass with your masters degree: maybe... It's up to your committee to decide. You need to discuss this with your advisor and committee members ahead of time.

It might be, if you can show a significant improvement over existing methods for said samples. If you can't do anything special with your "labour intensive" technique, it seems to have little merit.

    The technique itself is not "labor intensive," testing it in the scenario it's designed for (human interaction) is.
