Study Notes
Methods of Collecting Primary Data
- Observation method
- Interview method
- Through questionnaires
- Through schedules
- Other methods include:
- Warranty cards
- Distributor audits
- Pantry audits
- Consumer panels
- Using mechanical devices
- Through projective techniques
- Depth interviews
- Content analysis
Case Study
- Involves taking individual cases and conducting a detailed study of each
- Advantages:
- Provides accurate data
- Detailed analysis
- Disadvantages:
- Difficult to generalize
- Time-consuming
- Confidential and sensitive information may not be given
- Interviewer bias may be present
Research Approaches
Quantitative Research Approach
- Involves generating data in quantitative form
- Can be subjected to rigorous quantitative analysis
- Sub-classified into:
- Inferential approach
- Experimental approach
- Simulation approach
Inferential Approach
- Forms a data base from which to infer characteristics or relationships of population
- Usually involves survey research
- A sample of population is studied to determine its characteristics
Experimental Approach
- Characterized by greater control over research environment
- Variables are manipulated to observe their effect on other variables
Simulation Approach
- Involves constructing an artificial environment to generate relevant information and data
- Permits observation of dynamic behavior of a system under controlled conditions
- Can be useful in building models for understanding future conditions
Qualitative Research Approach
- Concerned with subjective assessment of attitudes, opinions, and behavior
- Research generates results in non-quantitative form or not subjected to rigorous quantitative analysis
- Techniques used include:
- Focus group interviews
- Projective techniques
- Depth interviews
Ex-post Facto Research (Empirical Research)
- Examines the relationship between independent and dependent variables
- Researcher has no control over independent variable
- Involves observing a variable and trying to find a causal variable that caused it
Action Research
- Conducted to solve a problem
- Involves direct action
- Example: Test marketing a product
Evaluation Research
- Conducted to find out how well a planned program is implemented
- Deals with evaluating the performance or assessment of a project
- Example: Evaluating a rural employment program or a midday meal program
Library Research
- Conducted to gather secondary data
- Includes notes from past data or a review of reports already conducted
- Convenient method that saves manpower and time
