, Introduction
• The scientific method is firmly based on the empirical
approach.
• Empirical approach is an evidence-based approach that
relies on direct observation and experimentation in the
acquisition of new knowledge
• In the empirical approach, scientific decisions are made
based on the data derived from direct observation and
experimentation.
• For example, we have all made decisions based on
feelings, hunches, or “gut” instinct.
, Types of Research
• Applied Research: Research done with the intention of
applying the results of its finding to solving specific
problems currently being experienced in the organisation.
• Basic Research: Research done with the intention to
generate more knowledge and understanding of the
phenomena that occur and to build theories based on the
research results.
Both types of research follow the same steps of systematic
inquiry to arrive at solutions to problems.
, STUDY DESIGNS
• Epidemiologic studies broadly classified as:
a) Observational - Non-Interventional
b) Experimental - Interventional
