    Study Notes

    Indirect Observables

    • Requires nuanced and indirect observations.

    Constructs

    • Theoretical creations based on observations but cannot be observed directly or indirectly.
    • Examples include IQ, which is a measure of cognitive ability.

    Concepts

    • Derived from mental images and observations.
    • Represented as "constructs."
    • Summarize related observations and experiences.
    • Reification: mistaking constructs for real entities.

    Conceptualization

    • Clarifies and defines fuzzy concepts.
    • Establishes indicators to represent the concept.
    • Indicates the presence or absence of the concept.

    Indicators

    • Used to assess specific concepts through observations.
    • Examples: giving food to homeless people is an indicator of compassion.

    Dimensions

    • Categorizes the different aspects of a concept.
    • Creates groups with shared characteristics.
    • Example: economic, social, and political dimensions of compassion.

    Interchangeability of Indicators

    • This principle suggests that multiple indicators of a concept should behave in the same way because they represent the same underlying phenomena.

    Definitions

    • Real definition: attributes essential characteristics to a concept, leading to reification.
    • Nominal definition: arbitrarily assigns meaning to a term without claiming it represents a real entity.
    • Operational definition: specifies how a concept will be measured in a study, emphasizing clarity and precision.

    Measurement Steps

    • Conceptualization
    • Nominal Definition
    • Operational Definition
    • Measurements in the Real World

    Reliability

    • Refers to the consistency of a measurement.
    • Methods to assess reliability include:
      • Test-retest method
      • Split-half method
      • Established measures
      • Reliability of research workers

    Validity

    • Assesses whether a measure actually reflects the concept it is intended to measure.
    • Types of validity include:
      • Face validity
      • Criterion-related validity
      • Construct validity
      • Content validity

    External Invalidity

    • Concerns the generalizability of research findings to the real world.
    • Factors contributing to external invalidity include:
      • Testing situation interaction with the experimental stimulus
    • Solomon four-group design, a research method, addresses this problem.
    • Post-test-only group design is another method that aims to address external invalidity.

    Field Experiments

    • Conducted in natural settings outside the laboratory.
    • World Wide Web has become a common platform for field experiments.

    Natural Experiments

    • Occur naturally within social life.
    • Social researchers can use these experiments in similar ways to laboratory experiments.

    Strengths and Weaknesses of the Experimental Method

    • Strengths:
      • Isolates independent variables, enabling causal inferences
      • Relatively easy to replicate
      • Scientific rigor
    • Weakness:
      • Artificiality; findings might not reflect real-world situations

    Ethics and Experiments

    • Deception is commonly used in experiments.
    • Experiments can potentially harm subjects.

    Survey Research

    • A research method used for descriptive, explanatory, and exploratory purposes.
    • Focuses on individual people as units of analysis.

    Respondent

    • A person who provides data for analysis by responding to a survey questionnaire.

    Questionnaire

    • A document with questions designed to gather information for analysis.
    • Used in various research methods, including surveys, experiments, and field research.

    Question Forms

    • Questions and statements are used in questionnaires to determine respondents' attitudes and perspectives.

    Response Rate

    • The percentage of people participating in a survey calculated by dividing the number of participants by the number selected in the sample.
    • Also referred to as completion rate and return rate.

    Interview

    • A data-collection encounter where an interviewer asks questions to a respondent.
    • Interviews can be conducted face-to-face or by telephone.

    Advantages of Interview Surveys

    • Higher response rates compared to mail surveys.
    • Interviewer's presence reduces "don't know" and "no answer" responses.
    • Interviewers can clarify confusing questions.
    • Interviewers can observe respondents in addition to asking questions.

    Guidelines for Survey Interviewing

    • Appearance and demeanour:
      • Interviewers should dress similarly to their interviewees.
      • Interviewers should be pleasant.
    • Familiarity with questionnaire:
      • Interviewers should be able to read questionnaire items without errors.
      • Interviewers should be familiar with the specifications accompanying the questionnaire.
