Aims and hypothesis

• Independent variable

  > This is the variable manipulated or is changed by the researcher to see if it has an effect on the dependant variable
• Dependant variable

  > This is the variable that the researcher measures

  > To see the effect of the independent variable
• Aim

  > This is a general statement of what the researcher intends to investigate, the purpose of the study
• Hypothesis

  > This is a specific, testable statement in which the researcher predicts what will happen between the variables
• Directional hypothesis (one tailed)

  > The researcher predicts the direction that they think the results will go in
• Non-directional hypothesis (two tailed)

  > The researcher does not predict the direction that they think the results will go in

  > They just say there will be a difference
• Null hypothesis

  > This simply states that the results gained were due to chance and not the independent variable that the researcher manipulated
