design a study – is this a study that is realistic to accomplish (given a decent amount of resources)?
Have you described what you’d like to study clearly and is it focused on one particular data point?
Have you accurately described the population for this study (make sure you read the textbook, lots of students get this wrong)?
Have you accurately described a sound sampling method to collect the data (again, read the textbook, so many students don’t do this correct)? Don’t just write, “systematic sampling”; describe in detail how you would go about collecting the data. And convenience sampling is NOT random sampling. DON’T use convenience sampling!
Is this study something that others would be interested in? (Granted this is the most subjective part of the grading)
