    Kudos! One of the best videos on ANY subject I've viewed on KZread. First of all, the Reasearch Coach was fun and interesting to listen to! She actually has a personality. Secondly, the learning objectives were delivered in English. Not some stilted "academic speak" which was difficult to interpret. Thirdly, the information was interesting and informative! Many thanks. Brilliantly done!

    Hi Emma, I watched the videos as I went through my dissertation chapter by chapter. These videos, along with my own reading from research textbooks, and advice from my research supervisor has helped immensely. I received a distinction for my MBA dissertation. Many thanks to you and all the other presenters from Grad Coach for uploading these videos. It’s a godsend when doing a dissertation. Thank you ever so much. You played a big part in helping me get a distinction in my MBA.

    So if you are working in clusters without sampling frames and have a tight time and budget limit. What technique should we choose if it is too expensive and time-consuming to enumerate and the clusters are too disorganized to do systematic sampling?

    Thank you for your video. In case of convenience sampling, how can we know/explain the population?

  • @GradCoach

    With convenience sampling, you can't be sure the sample represents the entire population accurately. You can describe the people you did sample, but you can't confidently say they stand for everyone in the population. It's a trade-off for the ease and speed of collecting data. If you're using convenience sampling, be clear about its limitations when you talk about your findings.

    So, I'm reading a journal article about a small college library trying to determine why the college staff doesn't take advantage of using their ILL service. They've stratified the population to students, faculty, visitors, and staff. They're only interested in a particular strata (staff) though and only interviewed them by sending the entire college staff an emailed survey. Is that still considered a stratified sampling?
