Questions and Answers

What is Causal Comparative Research?

  • Research that determines the cause for existing differences in groups. (correct)
  • Research focused solely on experimental methods.
  • Research that manipulates variables to find cause-effect relationships.
  • Research that only uses retrospective data.

    • What is Retrospective Causal-Comparative Research?

    It starts with effects and investigates causes.

    What does Prospective Causal-Comparative Research investigate?

    It studies causes and investigates their effects.

    Causal-Comparative Research establishes cause-effect relationships.

    Study Notes

    Causal-Comparative Research Overview

    • Aims to identify causes or reasons for differences in groups or individuals.
    • Ex post facto design: researchers analyze existing differences without manipulation.

    Types of Causal-Comparative Research

    • Retrospective Causal-Comparative Research:

      • Focuses on effects first, then investigates causes.
      • Common in education (e.g., comparing stress levels between those in and not in an exercise program).

    • Prospective Causal-Comparative Research:

      • Begins with potential causes and looks into their effects.
      • Example: Comparing self-esteem in middle school children based on their prior dance class attendance.

    Key Characteristics of Causal-Comparative Research

    • Does not establish clear cause-effect relationships; rather, it identifies correlations.
    • Typically involves multiple groups and at least one dependent variable.
    • Independent variables are pre-existing and not manipulated by the researcher.

    Variables in Causal-Comparative Research

    • Organismic Variables: Age, ethnicity, sex.
    • Ability Variables: Achievement levels.
    • Personality Variables: Self-concept.
    • Family-Related Variables: Socioeconomic status (SES).
    • School-Related Variables: Type and size of school.

    Limitations of Causal-Comparative Research

    • Limited control over variables by the researcher.
    • Interpretation of results must be cautious due to inability to establish definite cause-effect chains.

    Practical Applications

    • Useful for scenarios where manipulation of variables is impractical or unethical.
    • Can enhance decision-making and provide insights for future experimental studies.
    • Less costly compared to experimental studies.

    Conducting a Causal-Comparative Study

    • Involves selecting two distinct groups based on a variable of interest for comparison.
    • Critical to define and select comparison groups accurately.
    • Grouping variables must be operationally defined for clear differentiation.
    • Comparable groups reduce potential extraneous explanations for findings.

    Basic Study Designs

    • Group Exposure:
      • One group experiences an independent variable while the other does not; both measured on a dependent variable.
    • Dual Group Exposure:
      • Two groups receive different independent conditions, followed by measurement on the dependent variable.

    Control Procedures for Enhancing Research Validity

    • Matching:

      • Groups can be equated on specific variables to control confounding factors (e.g., pairing high achievers in instructional studies).

    • Homogeneous Group Comparison:

      • Focuses on groups that share similar characteristics regarding extraneous variables for more accurate comparisons.

    • Analysis of Covariance (ANCOVA):

      • Adjusts scores on dependent variables based on initial differences in related variables, enhancing the validity of conclusions.

    Data Analysis and Interpretation

    • Utilizes both descriptive and inferential statistics for data assessment.
    • Descriptive statistics frequently measure means and standard deviations.
    • Common inferential tests include t-tests, analyses of variance (ANOVA), and chi-square tests.
