How to develop hypotheses for research
of these so that one is necessarily accepted and the other rejected. Thanks for your feedback! If your prediction was correct, then you would (usually) reject the null hypothesis and accept the alternative. One of the independent concepts is positively related and the other negatively related to the dependent concept. It is a specific, testable prediction about what you expect to happen in a study. Unlike correlational studies, which can only be used to determine if there is a relationship between two variables, experimental methods can be used to determine the actual nature of the relationship. Two, hypotheses carry clear implications for testing the stated relationships. How does applying fertiliser affect the yield of a wheat crop grown on the North Downs in Kent? Which is tested against the alternative hypothesis: HA: As a result of 300mg./day of the ABC drug, there will be a significant difference in depression.
When writing up these results, the researchers might suggest other options that should be explored in future studies. In other situations, the results of the study might fail to support the original hypothesis. Your two hypotheses might be stated something like this: The null hypothesis for this study is: HO: As a result of the XYZ company employee training program, there will either be no significant difference in employee absenteeism or there will be a significant increase.

In some cases, the original hypothesis will be supported and the researchers will find evidence supporting their expectations about the nature of the relationship between different variables. Usually a hypothesis takes the form 'X causes Y' or 'X is related to Y'.
