We must avoid any reference to results proving a theory as this implies 100% certainty, and there is always a chance that evidence may exist which could refute a theory.Let’s consider a hypothesis that many teachers might subscribe to: that students work better on Monday morning than they do on a Friday afternoon (IV=Day, DV=Standard of work).A hypothesis statement needs to be formulated very carefully as it determines the direction of your research and forms the core idea, which motivates your research further.

Forming a hypothesis carries utmost importance in the scientific method of analyzing nature. One is a possible explanation of the phenomenon and the second is a testable prediction. Try to make it as specific as possible and make sure that all the information included in there is accurate.It states results are due to chance and are not significant in terms of supporting the idea being investigated.A two-tailed non-directional hypothesis predicts that the independent variable will have an effect on the dependent variable, but the direction of the effect is not specified.It is a great opportunity to challenge your mind to think out of the box and come up with a possible explanation for any observable phenomenon.To put it in the simplest of words, it is a 'guess', made to explain any phenomenon in nature.Now, if we decide to study this by giving the same group of students a lesson on a Monday morning and on a Friday afternoon and then measuring their immediate recall on the material covered in each session we would end up with the following: The null hypothesis is, therefore, the opposite of the alternative hypothesis in that it states that there will be no change in behavior.At this point, you might be asking why we seem so interested in the null hypothesis.When you see something weird happening and guess about what could have caused it, you are actually formulating one.However, hypotheses are informed and logical guesses, arrived at, after observing the relevant phenomenon in the most minute of details.Surely the alternative (or experimental) hypothesis is more important? However, we can never 100% prove the alternative hypothesis.What we do instead is see if we can disprove, or reject, the null hypothesis.
