  1. What’s the difference?Qualitative & Quantitative Research

  2. Value quantitative qualitative Potential benefits Drawbacks Tutorial Framework

  3. To Distinguish between Qualitative & Quantitative use: • Philosophical assumptions • methods of data collection • techniques of data analysis

  4. Quantitative positivist paradigm reductionism complex to simple deterministic cause & effect objective deductivism Qualitative rationalist paradigm holistic belief that researcher influences study varies subjective inductivism Philosophical Assumptions:

  5. Selecting Methods of investigation is not a neutral, value free or haphazard exercise... ...it reflects the values and beliefs of the researcher

  6. Quantitative questionnaires observation schedules other measuring tools knowledge, skills, attitudes, physiological & biochemical changes predetermined structured standardised Qualitative semi and unstructured interviews & observations flexible less structured researcher as tool fieldnotes Methods of Data Collection

  7. Quantitative measurement values & numbers central eg. Likert scale statistical tests wherever possible Qualitative seeks to “make sense” values not given to concepts Techniques of data analysis

  8. Human Phenomena has 2 sides: • the objective reality as it is manifested and observed by others and • the person’s subjective experience of the phenomenon

  9. Value of Quantitative Research • large samples • valuable data (demographic & epidemiologic) within a short time • links between variables measuring various concepts • suitable to study technical aspects (Horsfall 1995)

  10. Value of Qualitative Research • Context specific • cultural, social environmental • Values participant’s view • seeks to understand their world • Belief in the empowerment of participants

  11. Quantitative Difficult to ‘measure’ the human experience only provides a partial view of the phenomena Qualitative interactive nature researchers not objective lacks reproducibility Critique of Research Methods

  12. Using the same criteria to assess different research approaches is misleading as the purpose of each is different. • Quantitative researchers use large probability samples to generate data that can be generalisable to other settings. • Qualitative researchers seek to describe people’s experiences considered as unique, context related and not replicable.
