Step 1-4
• The broad problem area
• Preliminary data gathering
• Problem definition
• Theoretical framework
Step1:The broad problem area
• 1 Observation
• a problem currently existing
• A situation requiring improvement
• To find some answer empirically
• The broad problem area would be narrowed down
to specific issues for investigation after some
preliminary data are gathered by the researcher.
Step2:Preliminary data gathering
(Literature review)
• Types of data
– Primary data
– Secondary data
• Nature of data to be collected
– Background information of the organization
– Managerial philosophy, company policies
– Perception,attitudes,behavioral
responses,client systems
– Relevant surveys or research
Step3:Problem definition
• Or problem statement is a clear, precise,
and succinct statement of the question
or issue that is to be investigated with
the goal of finding an answer or
solution.
• Ex.What are the components of “quality of
life”?
Step4: Theoretical framework
• Is a conceptual model of how one theories
or make logical sense of the relationships
among the several factors that have been
identified as important to the problem.
• Then hypotheses can be developed
• Variables
– Dependent variable
– Independent variable
• Variables
– Dependent variable is the variable of primary
interest to the researcher.The researcher’s
goal is to understand and describe the
dependent variable.
– Independent variable is one that influences
the dependent variable in either a positive or
a negative way.
Ex.The development of a successful new
product influences the stock market price.
Survey Research

• Types Of Questions
• Survey questions can be divided into two broad types: structured
and unstructured

Probability Sampling
A probability sampling method is any method of sampling that utilizes some
form of random selection
