The current study has attempted to interpret the subjects’ experiences and find reasoning in both students and parents/ carers’ approaches. For this reason, following a mixed method approach has been identified as the most reliable approach. Paley (2000), expresses an unambiguous definition of both the qualitative and quantitative approach. Quantitative research presumes that there is an objective truth and a singular absolute reality. However, qualitative research perceives the reality as a place which is inherently subjective with no absolute reality (Paley, 2000).
The benefits of using quantitative research according to are briefly described below:
reduce the researcher’s biases there is no direct contact with the participant (Paley, 2000).
The disadvantages that the author underlines are:
the collected data will either support or reject the fixed paradigms,
the researcher’s detachment from the subjects can be a disadvantage as it does not offer the opportunity for an in-depth investigation (Paley, 2000).
According to Robson (2002), the validity refers to whether the findings are "real" to what they appear to be. The generalisability refers to the extent in which the findings of the investigation are generally applicable, outside the specific conditions of the condition study (Robson, 2002). According to Cohen, Manion & Morrison (2011) in qualitative data collection the subjectivity of the participants, their ideas, attitudes contribute all together to a degree of bias.
