dept’s, organisational records and data

3. PURPOSE OF SECONDARYDATA
 •Extracting the relevant information from other sources, previous

variables
 •Data mining: exploring data through computer. Using computer
technology to go through volumes of data to discover trends about
an organisation’s sales customers and products

•Extracting the relevant information from other

•Fact findings: descriptive information to support

. Data may be outdated(one can only hope that
the data is of good quality)

10. USES OF SECONDARY DATA
•Identify the problem
•Better define the problem
•Develop an approach to the problem
•Formulate an appropriate research
design
•Answer certain research questions and
test some hypothesis
•Interpret primary data more insightfully
