data
Internal
sources
Internal
o Many institutions and departments
have information about their
regular functions, for their own
internal purposes.
o When those information are used
in any survey is called internal
sources of data.
External
o When information is
collected from outside source.
o Such types of data are either
primary or secondary.
o This type of information can be
collected by census or
sampling.
Internal vs. External Sources of Data
▪ Collected from first-hand experiences is known as primary data.
More reliable, authentic and not been published anywhere.
▪ Primary data has not been changed or altered by human
being, therefore its validity is greater than secondary data.
Primary Data
Primary Research Methods and Techniques
Surveys
◼Personalinterview
(intercepts)
◼Mail
◼In-house,self-
administered
◼Telephone,fax,e-
mail,Web

Greater control
Demerits
Cost
Time
More personnel / resources
Inaccurate feedback
Training, skill and
laborious.
Primary Data
✓ Already been collected by others.
✓ Journals, periodicals, research publication ,official
record etc.
✓ May be available in the published or unpublished
form.
✓ Resorted to when primary data sources/methods are
infeasible -, inaccessible.
Secondary Data
Published
International
Government
Corporation
Institutional
Unpublished
Method of collection: secondary data
Merits
Quick and cheap
Wider geographical area
Leading to primary data
Demerits
Not fulfilling specific
research needs
Poor accuracy
Not up to date
Longer orientation period
Poor accessibility in some
cases
Secondary Data
Primary data
▪ Real time
▪ Sure about the sources
▪ Can answer research
question.
▪ Cost and time
▪ Can avoid bias
▪ More flexible
Secondary data
o Past data
o Not sure about sources
o Refining the research
problem
o Cheap and no time
o Bias can’t be ruled out
o Less flexible
Primary vs. secondary data
Thank you
