Research Methods

    Cards (17)

    • Experimental research involves manipulating variables and measuring the effects on other variables.
    • Purpose and procedures of random allocation ?
      purpose: this removes bias and controls participant variables
      procedure: participants are picked out at random and put in groups to complete conditions
    • Purpose and procedures of randomisation?
      purpose: reduces predictability
      procedure: presentation of stimuli are ordered randomly by the hat method
    • Procedures and purpose of standardisation?
      purpose : to keep EVERYTHING the same to ensure equality
      procedure: researcher keeps EVERYTHING the same
    • What is the purpose and procedure of counterbalancing ?
      purpose: equally distributes order of effects
      procedure: participants are grouped and complete the conditions in different orders
    • How can you make it easier to replicate the research?
      Operationalisation
    • whats counterbalancing?
      Participants are grouped and then each group completes the conditions in a different order
    • What’s an extraneous variable?
      Any variable other than the Independent variable that could affect the dependent variable
    • What’s a confounding variable ?
      a variables that varies with the Independent variable and affects the dependent variable
    • what are task variables?
      when participant’s complete multiple conditions so their performance could be affected
    • What are situational variables ?
      when participant’s performance could be affected by differences in the situation
    • What’s the independent groups design?
      different participants take part in each condition of the experiment
      used to compare one group to another
    • whats is the Repeated measures design ?
      Same participants take part in all conditions
      used to compare participants before and after performance
    • What’s the matched pairs design ?
      Different participants take part in each condition of the experiment
      however these participants are matched on key variables that could affect the dependent variable
    • What’s objectivity ?
      operationalising the variables so there’s no subjectivity making the research objective
    • What’s replicability?
      Operationalising the variables to make it easy to replicate the research
    • What is the experimental method ?
      manipulating the IV
      resulting in 2 conditions
      these conditions are then measured
      they're then compared for a difference
      if there’s a difference we can establish cause and effect
