Compare and contrast qualitative and quantitative approaches to research
This essay will compare and contrast the 3 articles below in relation to qualitative and quantitative approaches to research focusing on the design and methods used in each study including sampling, data collection and data analysis. The first chosen article by Winkens et al. (2006) uses a qualitative method to look at the manifestations of mental slowness in the stroke population. Toulotte, Thevenon, Watelain and Fabre (2006) uses a case comparison quantitative study to identify healthy elderly fallers and non-fallers by gait analysis under dual task conditions and the study by Girou, Loyeau, Legrand, Oppein and Brun-Buisson (2002) uses a randomised clinical…show more content… The use of semi-structured questionnaires has many advantages and disadvantages.

Using this approach can cause inconsistencies between the interviews and therefore can effect the outcome of the interview. Every effort should be made to keep the questioning similar. If a discussion is made in one interview then that topic should be made available to the next
