approach to ‘qualitative research’ or ‘interpretive research’, and is an attempt to ‘unearth’ a Notes
theory from the data itself rather than from a pre-disposed hypothesis.
There are three types of objective in a marketing research project.
• Exploratory Research

• Descriptive research
• Causal research

Exploratory Research: ‘The objective of exploratory research is to gather preliminary information
that will help define problems and suggest hypotheses.’
Descriptive Research: ‘The objective of descriptive research is to describe things, such as the
market potential for a product or the demographics and attitudes of consumers who buy the
product.’

Causal Research: ‘The objective of causal Research is to test hypotheses about cause-and-effect
relationships.

Task Explain the most common computer science research method.

3.1.2 Constructive Research

Constructive research is perhaps the most common computer science research method. This
type of approach demands a form of validation that doesn’t need to be quite as empirically
based as in other types of research like exploratory research.
Nevertheless the conclusions have to be objectively argued and defined. This may involve
evaluating the “construct” being developed analytically against some predefined criteria or
performing some benchmark tests with the prototype.
The term “construct” is often used in this context to refer to the new contribution being
developed. Construct can be a new theory, algorithm, model, software, or a framework.
