- Take notes on definition of non directional hypothesis
- Take notes on definition of directional hypothesis
- Follow structure in booklet through a worked example of creating a hypothesis
- Using example in booklet for directional hypothesis try writing a hypothesis for two experiments.

Content Recap:
Hypotheses: States what you believe is true. It is a precise and testable statement of the relationship between two variables. It is a statement, not a question or a prediction.
Directional Hypothesis: States the direction of the predicted difference between two conditions or two groups of people in a precise and operationalised way. Also known (for statistical tests) as a one tailed hypothesis. E.g. “Participants who IV (a) will state how the DV will differ compared to participants who IV (b) ”
Non-Directional Hypothesis: States that there is a predicted difference between two conditions or two groups of people in a precise and operationalised way without stating what that difference will be. Also known (for statistical tests) as a two tailed hypothesis. E.g.“There will be a difference in DV performance between IV (a) and IV (b)”
