Great that your doing psych( great subject!):

I think it is good to know! (ie. advantages= more represtitive sample, disadvantages:  practical constraints in terms of time available)>> thats not a very good one, but i cant seem to remember any more :)

 It may help knowing especially with the first SAC ( research report) , other research methods SACs and more importantly , the exam! :)

Advantages:
  • Cheap
  • Quicker (selecting the sample takes less time and time = money)
  • Equal chance of getting selected

Disadvantages
  • May not correctly represent all populations

That's all I can think of at the moment. It should be in your psych book. Which book are you using?
