10 Presenting results – in development
ACTION: You now need to
consider how you may be presenting the results of your research
Hypothesis tests typically enable you to decide between two hypotheses based on the probability of the experimental evidence recorded.
The Null Hypothesis is normally that the observed evidence could have occurred just by chance.
The Proposed (or Alternative) Hypothesis is that the observed evidence occurred due to the effect that you are inestigating.
If you use software to perform the test, then you will normally get a p-value.
If p < α, where α is the significance level that you set (normally 0.05), then you would accept the Proposed (or Alternative) Hypothesis
If p > α, then you would state that, on the basis, of the experimental evidence it is not possible to Reject the Null Hypothesis.
