๐Ÿง  Quick Study Guide

  • ๐Ÿงช Independent Variable (IV): The variable manipulated by the researcher.
  • ๐Ÿ“Š Dependent Variable (DV): The variable being measured; its value depends on the IV.
  • ๐Ÿง‘โ€๐Ÿ”ฌ Control Group: A group in an experiment that receives no treatment; used as a baseline for comparison.
  • ๐ŸŽ Experimental Group: The group that receives the treatment or manipulation.
  • ๐ŸŽฒ Random Assignment: Assigning participants to experimental and control groups randomly to minimize bias.
  • โš–๏ธ Confounding Variable: A variable that influences both the independent and dependent variables.
  • ๐Ÿ“ Operational Definition: Defining variables in measurable terms (e.g., reaction time measured in milliseconds).
  • ๐Ÿ“Š Between-Subjects Design: Different participants are used in each condition.
  • ๐Ÿ”„ Within-Subjects Design: The same participants are used in all conditions.
  • โฑ๏ธ Counterbalancing: A technique used in within-subjects designs to minimize order effects (e.g., ABBA design).
  • ๐Ÿ“‰ Internal Validity: The degree to which an experiment measures what it intends to measure, free from confounding variables.
  • ๐Ÿ“ˆ External Validity: The extent to which the results of a study can be generalized to other situations and to other people.

Practice Quiz

  1. Which of the following is the variable that is manipulated by the researcher?
    1. A. Dependent Variable
    2. B. Independent Variable
    3. C. Confounding Variable
    4. D. Control Variable
  2. What is the purpose of a control group in an experiment?
    1. A. To receive the experimental treatment
    2. B. To serve as a baseline for comparison
    3. C. To introduce bias into the study
    4. D. To manipulate the independent variable
  3. Random assignment is used to:
    1. A. Ensure all participants receive the same treatment
    2. B. Minimize pre-existing differences between groups
    3. C. Systematically assign participants based on characteristics

    3. C. A variable that remains constant throughout the experiment
    4. D. A variable that only affects the dependent variable
  5. In a between-subjects design:
    1. A. The same participants are used in all conditions
    2. B. Different participants are used in each condition

    1. A. The number of participants needed
    2. B. Order effects in within-subjects designs
    3. C. The impact of the independent variable
    4. D. The cost of the experiment
  7. What does internal validity refer to?
    1. A. The extent to which results can be generalized
    2. B. The degree to which an experiment measures what it intends to measure
    3. C. The consistency of the experimental procedure
