Random sampling versus randomisation

I recently examined a MPH thesis in which the student stated that “the intervention and control were assigned using a random sampling technique.” I have noted in the past that students mix-up random sampling and randomization. I therefore explain both concepts together in this article. continue reading

Oral presentation skills

I have posted formats that I developed for a quantitative research proposal and article on my website and I have received many comments from students/professionals that these have been very helpful.
