One of the essential statistical considerations for the dissertation proposal is sample size justification. Your committee wants to know that your sample size is adequate to address your research questions. The way to justify a sample size is with a statistical power analysis. See my Power Analysis Tutorial for more information.
In basic terms, a power analysis determines how likely it is that you could detect a significant difference - that is, achieve statistically significant results - with a given sample size.
When you hire me to help with your Dissertation Proposal, I will tutor/advise you and write all of the statistical considerations for you, including a power analysis and sample size justification section. I also include unlimited email and telephone support to answer any questions that you might have about the statistics that I propose for your study (except in the event of my incapacitation, death or the demise of my business).
Simply contact me by phone or email to get started.
