Alternate Hypothesis (Experimental Hypothesis): A specific testable statement that predicts the expected outcome of a study. An alternate hypothesis states that there will be a difference/relationship between the variables being investigated.
Null Hypothesis: States there will be 'no specific difference' or 'no significant relationship' between variables under investigation.
One-tailed hypothesis: Predicts the direction that the difference will take. It is directional. E.g. particpants under the age of 30 year will recall significantly more items than particpants aged 60 or above.
Two-tailed hypothesis: Non-directional. Merely states that there will be a signifcant difference between those particpants given a categorised list compared to those given a randomised list. E.g. There will be a significant difference between those participants given a categorised list compared to those given a randomised list.
Correlational hypotheses: Predict significant patterns of relationship between two or more variables. Involves co-variables not independent and dependent variables.
