The research is about how stress affect University student's diet.
What are some of the limitations for a QUALITATIVE research?
You can't control extraneous variables so you never know how external factors are influencing peoples answers e.g. wanting to appear socially desirable. The presence of an interviewer may influence how the participant responds. It also takes a great deal of skill to manage an interview etc effectively and it is also time consuming and difficult to interpret data. The data can be difficult to analyse objectively and their is no data to quantify. It is also difficult to replicate.
Reply:Well, just as an example....
Some people who eat what they consider a "good diet" eat deep fried foods every day - and on average, eat only two servings of vegetables per day - french fries and ketchup.
Then there are others who eat 10 servings of fruits and veggies, 6 servings of whole grains, never smoke, drink cofee or booze, etc.
