A college/university teacher plans to test his/her substantive research hypothesis in a major project. Which of the following statements are considered relevant in this regard?

A. Substantive research hypothesis has to clearly specify the relationship among variables

B. Research hypothesis may be directed at finding out differential effects or relationships

C. Null hypothesis should be formulated beforehend

D. There is direct support available for testing the substantive research hypothesis

E. The final decision on the research hypothesis may be reached indirectly by deciding the fate of the Null hypothesis

Choose the correct answer from the options given below:

Substantive research hypothesis:

• According to F.N. Kerlinger, A Hypothesis is a description of the relationship between two or more variables.
• A hypothesis is an idea that the researcher pre-establishes as the goal of the study and examines it and is replaced as a theory when the hypothesis is true in the study's conclusion
• Subject matter knowledge and theories lead to expectations regarding the type, strength, or possibly the sign of some of the associations and to hypotheses about relations that are only indirect.
• Such expectations and hypotheses picturing actual properties of observational units are called substantive research hypotheses or simply research hypotheses.
• It demonstrates that the researcher has some prior knowledge about the research study
• It provides direction for data collection and its interpretation
• In the evaluation of the hypothesis, it should be explained with the movement of study, the anticipated relationship between variables
• It must be testable and to be proven wrong. The study adopted techniques should be capable to test the hypothesis whether it is true or false
• The final decision on the research hypothesis may be reached indirectly by deciding the fate of the Null hypothesis. 
• Here the Null hypothesis is not formulated beforehand.

Therefore A, B and E only is the correct answer.
