* Why and when should a startup company gather secondary versus primary data to validate the business case?
http://www.managementstudyguide.com/secondary_data.htm
Secondary data is the data that have been already collected by and readily
available from other sources. Such data are cheaper and more quickly obtainable
than the primary data and also may be available when primary data can not be
obtained at all.
Advantages
of Secondary data
It is
economical. It saves efforts and expenses.
It is time saving.
It helps
to make primary data collection more specific since with the help of secondary
data, we are able to make out what are the gaps and deficiencies and what
additional information needs to be collected.
It helps
to improve the understanding of the problem.
It
provides a basis for comparison for the data that is collected by the
researcher.
Disadvantages
of Secondary Data
Secondary
data is something that seldom fits in the framework of the marketing research
factors. Reasons for its non-fitting are:-
Unit of
secondary data collection-Suppose you want information on disposable income,
but the data is available on gross income. The
information may not be same as we require.
Class
Boundaries may be different when units are same.

7500-10000
7001-10000
Thus the
data collected earlier is of no use to you.
Accuracy
of secondary data is not known.
Data may be outdated.
Evaluation
of Secondary Data
Because
of the above mentioned disadvantages of secondary data, we will lead to
evaluation of secondary data. Evaluation means the following
four requirements must be satisfied:-
Availability- It has to be seen that the kind of data you want is available or
not. If it is not available then you have to go for primary data.
Relevance- It should be meeting the requirements of the problem. For this we have two criterion:-
Units of
measurement should be the same.
Concepts
used must be same and currency of data should not be outdated.
Accuracy- In
order to find how accurate the data is, the following points must be
considered: -
Specification and methodology used;
Margin
of error should be examined;
The
dependability of the source must be seen.
Sufficiency- Adequate data should be available.
Robert W
Joselyn has classified the above discussion into eight steps. These eight steps
are sub classified into three categories. He has given a detailed procedure for
evaluating secondary data.
Applicability of research objective.
Cost of acquisition.
Accuracy of data.
_________________
A common classification is based upon who collected the data.
Primary data: Data collected by the investigator
himself/ herself for a specific purpose.
Examples: Data collected by a
student for his/her thesis or research project.
(In movies) The hero is directly told by the heroine that he is her
“ideal man”.
Secondary data: Data collected by
someone else for some other purpose (but being utilized by the investigator for
another purpose).
Examples: Census data being used
to analyze the impact of education on career choice and earning.
(In movies) The hero reads a fictional account of the heroine’s “ideal
man” (written for a course in English composition) that seems to describe him
accurately. He seeks confirmation from his friends, concluding that he is her “ideal man”. (He never asks her
directly, but assumes the “facts” are correct).
Some Advantages of using Primary data:
The investigator collects data specific to the problem under study.
There is no doubt about the quality of the data collected (for the
investigator).
If required, it may be possible to obtain additional data during the
study period.
Some Disadvantages of using Primary data (for
reluctant/ uninterested investigators):
The investigator has to contend with all the hassles of data
collection-
deciding why, what, how, when to collect
getting the data collected (personally or through others)
getting funding and dealing with funding agencies
ethical considerations (consent, permissions, etc.)
2. Ensuring the data collected is of a high standard-
all desired data is obtained accurately, and in the format it is
required in
there is no fake/ cooked up data
unnecessary/ useless data has not been included
