Research Methods

• aim


  - a clearly phrased general statement about what the investor intends to research
• hypothesis


  - a precise testable statement including levels of the IV and DV (or both co-variables for a correlational study)
• non-directional (two-tailed) hypothesis


  - states that there is a difference in the measurement of the DV, but not the direction the results will go
• directional (one-tailed) hypothesis


  - states that there is a difference in the measurement of the DV, and says which direction the results will go (increase/decrease)

  - should only use when there is previous research which suggests the way results are likely to go
