ANS: Why should an investigator need to consider some precautions before using secondary data

Since secondary data have already been obtained it is highly desirable that a proper scrutiny of such data is made before they are used by the investigator. In fact, the user has to be extra-cautious while using secondary data. In this context, Prof. Bowley righty points out that secondary data should not be accepted at their face value. ‘’the reason is that such data may be erroneous in many respects due to bias, inadequate size of the sample, substitution, errors of definition, arithmetical errors etc even if there is no error such data may not be suitable and adequate for the purpose of the enquiry.
