    • What is correlation used to analyze?
      The relationship between two continuous variables
    • How can correlations be illustrated?
      Using a scatter diagram or scatter graph
    • What does a coefficient closer to 0 indicate?
      A weaker correlation
    • What does a coefficient closer to 1 indicate?
      A stronger correlation
    • What can correlations show about relationships?
      Both direction and strength of a relationship
    • When can correlations be used?
      When experiments are inappropriate
    • What is a limitation of correlation studies?
      They do not establish cause and effect
    • What is a case study?
      An in-depth study of a unique individual or group
    • What types of data are primarily collected in case studies?
      Mostly qualitative, sometimes quantitative
    • What is a characteristic of case studies?
      They are holistic and usually longitudinal
    • What is a strength of case studies?
      Produces rich qualitative data with high ecological validity
    • What is a limitation of case studies?
      Researcher bias can affect objectivity
    • Why is it difficult to generalize findings from case studies?
      The sample size is too small
    • What are self-reports?
      Methods where participants report information about themselves
    • What is a strength of self-reports?
      They provide insight into why people behave
    • What is a limitation of self-reports?
      Risk of social desirability bias
    • What can affect the accuracy of self-reports?
      Participants may not recall details accurately
    • What is quantitative data?
      Data that can be measured numerically
    • What is a strength of quantitative data?
      It is easy to analyze
    • What is a limitation of quantitative data?
      It loses the 'human' level of behavior
    • What is qualitative data?
      Data that can be observed but not measured numerically
    • What is a strength of qualitative data?
      It offers a more individualized view of behavior
    • What is a limitation of qualitative data?
      It can be difficult to analyze
    • What is a characteristic of primary sources?
      Data collected directly by the researcher
    • What is a strength of primary sources?
      The researcher controls the data collection format
    • What is a limitation of primary sources?
      Data may lack validity due to biases
    • What are secondary sources?
      Data not directly collected by the researcher
    • What is a strength of secondary sources?
      Data may be more valid without participant knowledge
    • What is a limitation of secondary sources?
      The researcher cannot control data format
    • What do CAT scans produce?
      2D or 3D images of the brain
    • What is injected into patients before a CAT scan?
      Radioactive dye
    • What do CT scans create?
      Cross-sectional images of the brain
    • What is a strength of CAT scans?
      They produce high-quality images
    • What is a limitation of CAT scans?
      They only show brain structure, not function
    • What is a risk associated with CAT scans?
      Exposure to radiation
    • What do PET scans use to show brain activity?
      Radioactive glucose
    • What do PET scans highlight?
      The most active areas of the brain
    • What is a strength of PET scans?
      They show chemical activity in the brain
    • What is a limitation of PET scans?
      They are costly to run and maintain
    • What characterizes longitudinal studies?
      Conducted over a long period of time
