  Qualitative Research Quantitative* Research
Objective / purpose: To gain an understanding of underlying reasons and motivations To provide insights into the setting of a problem, generating ideas and/or hypotheses for later quantitative research To uncover prevalent trends in thought and opinion To quantify data and generalize results from a sample to the population of interest To measure the incidence of various views and opinions in a chosen sample Sometimes followed by qualitative research which is used to explore some findings further
Sample Usually a small number of non-representative cases Respondents selected to fulfil a given quota Usually a large number of cases* representing the population of interest Randomly selected respondents
Data collection Unstructured or semi-structured techniques e.g. individual depth interviews or group discussions Structured techniques* such as on-street or telephone interviews
Data analysis Non-statistical Statistical*; data is usually in the form of tabulations Findings are conclusive and usually descriptive* in nature.
Outcome Exploratory and/or investigative Findings are not conclusive and cannot be used to make generalizations about the population of interest Develop an initial understanding and sound base for further decision making Used to recommend a final course of action
