Case Study

Explain how the researcher's design decisions demonstrate comprehension of the two major advancements in psychological survey methodology that emerged during the 19301930s.

Case context: An early psychological researcher in 19351935 is designing a study to investigate attitudes and prejudice towards minority groups. Traditionally, researchers in their department gather data from a small group of their own university students. However, this researcher decides to distribute a structured scale measuring agreement to a large group of workers, homemakers, and professionals from different neighborhoods in the city.

Question: Explain how the researcher's design decisions demonstrate comprehension of the two major advancements in psychological survey methodology that emerged during the 19301930s.

Sample answer: The researcher's design decisions directly reflect the two major 19301930s advancements: 1) Questionnaire design: Using a structured scale to measure agreement mirrors the development of scales like the Likert scale to study social attitudes. 2) Sampling methodology: Moving away from the university's own students to recruit a varied city sample represents the transition from convenience sampling of students to larger, more diverse participant groups pioneered by early attitude researchers.

Key points:

  • Connects the structured agreement scale to questionnaire design innovations (e.g., Likert scale).
  • Connects the recruitment of city workers to the pioneer use of larger, more diverse samples.
  • Contrasts the new sampling method with traditional convenience samples of university students.

Rubric: Grading Criteria: The student must explain how the structured agreement scale relates to questionnaire design advancements (such as the Likert scale) and how recruiting city residents instead of university students relates to the shift from convenience sampling to larger, more diverse samples. Both points must be explained in the context of 19301930s psychological research.
