Research Methods (STA630)
The Relationship between Theory and Hypothesis

In a classroom, a student presented his research paper. Once QA session started after the completion of the presentation, one of the students raised an objection on the study. The student objected the presenter that the hypotheses he presented are not valid as these are not derived from any theory. The hypotheses should have been linked with some theoretical framework to provide an explanation of event or phenomenon. The teacher intervened by saying that both of you are right and the difference is that both of you are thinking in different contexts. The students got surprised by the comment of teacher that how is it possible that two persons are right at the same time?

You as a student of research methodology build your arguments to justify your point of view with logic and to support the person who according to you is right (presenter, student, or teacher).

Special Instructions

· Give precise justification and reply should not exceed more than 150 words.
· Build your own argument based on your learning of Research Methods and do not use any cheating link.

SOLUTION IDEA:

Relationship between Theory and Hypothesis?

Answer
A hypothesis is a statement that can be tested (not yet proved) while a theory is an overall principle or body of principles that has been established to explain a wide variety of phenomena.

hypothesis and theoretical framework can be used interchangeably..

………..

Hypothesis should be related to a body of theory. Hypothesis has to be supported by theoretical argumentation. For this purpose the research may develop his/her theoretical framework which could help in the generation of relevant hypothesis. For the development of a framework the researcher shall depend on the existing body of knowledge. In such an effort a connection between the study in hand and the existing body of knowledge can be established.

That is how the study could benefit from the existing knowledge and later on through testing the hypothesis could contribute to the reservoir of knowledge.

………..

A THEORY is a well-established principle that has been developed to explain some aspect of the natural world. A theory arises from repeated observation and testing and incorporates facts, laws, predictions, and tested hypotheses that are widely accepted.

A HYPOTHESIS is a specific, testable prediction about what you expect to happen in your study. For example, an experiment designed to look at the relationship between study habits and test anxiety might have a hypothesis that states, “We predict that students with better study habits will suffer less test anxiety.” Unless your study is exploratory in nature, your hypothesis should always explain what you expect to happen during the course of your experiment or research.

A theory predicts events in general terms, while a hypothesis makes a specific prediction about a specified set of circumstances.

A theory has been extensively tested and is generally accepted, while a hypothesis is a speculative guess that has yet to be tested.
