How can you distinguish a researchable from a non-researchable problem?

1.Data are available and accessible. The researcher must be sure that the participants in his investigation posses the needed data and that they are within his reach. So,one must not choose a problem in which the locations of the data are too far away,say foreign lands.

2.Data must meet the standards of accuracy,objectivity,and verifiability.The data gathered must be accurate,objective,and not biased,and can be verified when there arises a need,otherwise the result of the study will not be valid and generalizations formulated will be faulty.

3.Answers to the specific questions(subproblems) can be found. The data to be collected must supply the necessary answers to the specific questions.

4.The hypotheses formulated are testable,that is,they can be accepted or rejected.

5.Equipment and instruments for research are available and can give valid and reliable results.
