Aims and hypotheses

• What is the criteria for stating aims?


  -needs to be developed before carrying out research

  -general statement which outlines what is being investigated

  -purpose of investigation
• What is the criteria for a hypothesis?


  -constructed to show research that doesn't support the experimental /alternative hypothesis

  - have a conclusion for results
• What is the purpose for the null hypothesis?


  -constructed to show research that doesn't support the experimental /alternative hypothesis

  - have a conclusion for results
• When would an experimental hypothesis be used?


  -when an experimental method is used

  - when there is an IV and DV
• What does and experimental hypothesis do?


  suggest there is a relationship between phenomena
• When is a non-experimental hypothesis used?


  when there is no IV or DV
• What does a directional hypothesis do?


  predict the direction of results (how much/fast/less/slow)
• When is a directional hypothesis used?


  when there is lots of previous research into the area so the researcher can make an informed decision
• What is a non-directional hypothesis?


  States the relationship exists, but not the direction (how fast/slow/more/less)
• When is a non-directional hypothesis used?


  when there is minimal / no research around that area (limited in previous research)
