- Abstract
Probability is the tool used to test null hypotheses (statements that observed effects were caused by chance rather than by the research intervention). We use the balance of probabilities to tell if something is found by chance. Perhaps a finding has occurred because of an action on our part, or perhaps it has occurred by chance. By using mathematical formulae, which determine probabilities, we can discover the likelihood of something occurring by chance, or by the action on our part. A probability of 1 is the highest, and If we say that it will rain, it gains a probability of 1, as it is most probabie that it will rain sometime. If we say it will rain in, say, England, that is also highly probable. If we become more specific, and say it will rain in England tomorrow, then the probability lessens. By saying that it will rain in Manchester at 12 midday, we lessen the probability even more because we have narrowed the field.
