While an investigator may have one or two hypotheses, which he might have deduced from theory, the study of available materials may suggest further hypothesis.
- 6. 3. Supplementary Information: Available documents may be used to supplement or to check information gathered specifically for the purposes of a given investigation. 4. Cost, Time and Effort Saving: The secondary data is the information that is already created by someone else. Therefore, it saves cost, time and effort. The researcher gets accurate and ready data. 5. Helps in Testing the Hypothesis: The available records may help in testing the hypothesis.
