Only testable hypotheses can be used to conceive and perform an experiment using the scientific method. Ibuprofen is more effective than aspirin in helping a person who has had a heart attack. A hypothesis describes a research study in correct terms and provides a basis that you can use to evaluate and prove the validity or invalidity of a specific research.

It prevents the researchers time as he does not need to waste time on reviewing the irrelevant research and literature, and also prevents the researcher from collecting the irrelevant data. Reviewing the similar studies and literature related to a similar problem. Note that until youre able to test a theory for an extended period, the evidence for any claim can only remain logical. Because hypothesis helps to analyze the scientific validity of research methodologies, researchers can assume an almost accurate probability of the progress of failure of a research. More importantly, you need to build a robust testable research hypothesis for your scientific experiments. 72 Comments Please sign inor registerto post comments.

Here, providing snack breaks is the independent variable and the employees are less likely to take the off-site break is the dependent variable. The two primary features of a scientific hypothesis are falsifiability and testability, which are reflected in an "Ifthen" statement summarizing the idea and in the ability to be supported or refuted through observation and experimentation .
