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.

Interviewers therefore have to ensure that the questions they ask are understood by the participants. In the stroke population the question of cognitive functioning was asked. It is not stated in the article how this question was asked.
