hypotheses

• A hypothesis states what you believe is true. It is a precise and testable statement of the relationship of two variables.
• There are different types of hypothesis which can be used based on how confident you are in your predictions:

  • Directional hypothesis (1 tailed)
  • Non-directional hypothesis (2 tailed)
  • Null hypothesis
• Directional/ one tailed hypothesis– states the direction of a predicted difference between 2 conditions
• Non directional/ two tailed hypothesis– states there will be a difference between 2 conditions but doesn’t specify how
• Null hypothesis– predicts there will be no significant difference between conditions
