        Within subjects design
        
        Advantages
        
        No individual participant differences
        
        Fewer participants needed
        
        Disadvantages
        
        Creates order effects
        
        Fatigue
        
        Counterbalance to correct
        
        Learning
      - Some are exposed to 1, and some are exposed to 2 or more
        
        Mixed design
        
        Advantages
        
        Allows for more comparisons between different groups of participants over time
        
        Disadvantages
        
        More costly, time-consuming, and difficult to set up
      - 1
        
        Between subjects design
        
        Disadvantages
        
        Subject to individual participant differences
        
        Cognitive ability
        
        Culture
        
        Sex
        
        Differences in variables that influence the DV
        
        Age
        
        Advantages
        
        Can be less time consuming
    - - Limited ecological validity; controlled setting may influence participant responses
      - Results may be influenced by experimenter biases and expectations
      - Time consuming and difficult to set up
        
        Extraneous and confounding variables can still influence results
    - - Causal relationships can be established
      - Researchers have a high level of control over variables
        
        Influence of extraneous and confounding variables are minimised
        
        Experiments can be easily repeated
- - - - Case study
        
        Advantages
        
        Can provide detailed information about unique, new, or rare phenomena
        
        Disadvantages
        
        Sample size is often small
        
        Limited generalisability
        
        Interpretations of results/data can be subject to experimenter biases as often only small teams of researchers can work on a case study
    - - Does the investigation observe and measure relationships between variables without manipulation?
        
        No
        
        Is information organised, arranged, or otherwise labelled?
        
        Yes
        
        Classification and identification
        
        Disadvantages

        Correlational study
        
        Advantages
        
        Provides information relating to relationships, associations, and correlations between variables
        
        Tend to have higher ecological validity (reflects real world scenarios more) as they are conducted in more naturalistic settings
        
        Easier to conduct than experiments as no manipulation of variables is required
        
        Less time consuming to conduct
        
        Questionnaires
        
        Does the study use observations in real world settings without modifying the environment?

        Interviews
        
        Surveys
        
        Focus groups
        
        Disadvantages
        
        Extraneous variables may influence results
        
        Causation cannot be determined as variables are not manipulated
