  • Experiment
    • 3 types
      • lab experiment
        • cotrolled IV in a controlled settings
          • control over IV and extraneouse variables
          • locks ecologcal validity and chance of demand characteristics
      • quasi experiment
        • natural IV in a controlled settings
          • IV natural so has ecological validity
          • artificial settings lowers ecological validity
      • feild experiment
        • controlled IV in a natural settings
          • natural settings increases the validity
          • natural settings hard to replicate
    • 3 types of data
      • ordinal data
        • data in order
      • nominal data
        • data in separate categories
      • interval
        • useing a unit of measurement
    • strengths
      • cause and effects
      • high control over extaneouse varibles
      • easy to replicate
    • 4 types of hypothesis
      • Null hypothesis
        • 'there will be no difference'
      • one tailed hypothesis
        • predicts the direction of results
      • two talied hypothesis
        • does not predicts the direction of the results
      • alternate hypothesis
        • states the expected results
    • weaknesses
      • demand characteristics
      • locks ecoloical validity
      • hawthorne effects
    • IV and DV
      • the IV is the variable been minipulated
      • the DV is the measured outcome
    • designs
      • independent measeures
        • different participants for each condition
          • no order effects
          • individual differences
      • repeated measures
        • same individual on two or more conditions
          • order effects and demand characteristics
          • no individual differences
      • matched paires
        • different participants for each condition
          • cotrolled participants variables
          • chance of demand characteristics
