Qualitative techniques on the other hand rely on devices such as ethnography, biography or case studies in the process of data collection. These methods allow the researcher to get the insider’s viewpoint of the matter in issue and not necessarily the objective truth. They allow the researcher to conduct in-depth studies of a specific group or individual chosen to represent social phenomena and allow the researcher to ‘access the reality behind appearances’. These techniques have the obvious advantage that they provide opportunities to verify responses by comparing a number of different approaches in resolving an issue. They allow for the complexities of social, legal and political interaction to be seen and for the relationships between these and the effects of one on the others to become more obvious. Furthermore, qualitative techniques allow the researcher to delve deeper into inconsistent responses and analyse significant situations at greater depth. The drawbacks for these techniques include the absence of statistical validity of a proper sample and objective quantitative proof. Furthermore, there is the omnipresent risk of people changing their positions or acting up because the know they are being studied. The data may also be more reflective of the researcher’s views rather than the subjects’ because there is more latitude for researcher bias in the actual choice of the individual or case to be examined.
