Non-Directional Hypothesis
Non-directional hypothesis testing is a statistical technique in which the researchers do not specify the direction of a relationship or difference between variables. Non-directional hypotheses are formulated when the researcher is interested in determining whether there is a statistically significant difference or relationship between variables, but they do not make specific predictions regarding the direction of the effect. It is open to the possibility that the effect may be positive or negative to the researcher.
The researcher does not predict whether the new teaching method will result in better or worse performance than traditional teaching methods in this hypothesis. Rather than comparing the performance of the two methods, they are simply looking for statistically significant differences.
