Solution
Qualitative and quantitative research are two distinct approaches to gathering and interpreting data.
Qualitative research is primarily exploratory, aiming to understand underlying reasons and motivations. It focuses on a specific group and the findings are generally not applicable to the entire population. The quality of qualitative research is determined by its trustworthiness, which includes credibility (confidence that the results are believable), transferability (the degree to which the research/results can be transferred to other contexts), dependability (ensuring that the research findings are consistent and could be repeated), and confirmability (degrees of neutrality, the findings are supported by data).
On the other hand, quantitative research aims to establish a relationship between variables in a population or a representative sample of the population using statistical, mathematical, or computational techniques. It involves two types of variables: independent variables (stand-alone and cannot be changed by other variables that you are trying to measure) and dependent variables (are affected by other factors or independent variables). The quality of quantitative research is determined by its reliability (consistency of the measure) and validity (whether the research measures what it is required to measure & performs as it is designed to perform). Validity can be further divided into internal validity (the degree to which the observed effects of the independent variable are real and not caused by external factors), construct validity (the completeness of the content and the extent to which the measures accurately assess what the research wants to establish), and external validity (the extent to which the results can be generalised beyond the study sample).
In summary, qualitative research is more subjective and interpretive, while quantitative research is more objective and statistical. Both approaches have their strengths and weaknesses, and the choice between them depends on the research question and the nature of the data.
