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:-
1. 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.
2. 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not be outdated.
1. 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.
2. 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.
