Introduction to Research Design and Explanatory Models
Components of Research Design
- Dynamic Relationship: The planned design and actual execution often differ due to unforeseen changes or regulations, yet a structured plan remains essential.
- Core Research Questions:
- What: Clearly specifying the exact phenomenon or topic to find out.
- Why: Establishing the broader purpose, context, and significance of the study.
- How: Deciding on data collection methods while balancing time, resources, and data quality.
- Framing Specific Questions: Moving beyond broad general topics to framed, specific research questions guides the choice of suitable methodology.
Types of Research Purposes
- Exploration:
- Focuses on new, unfamiliar, or emerging phenomena (e.g., quiet quitting emerging on TikTok in 2022 post-COVID).
- Provides preliminary insights rather than representative or population-level national trends.
- Description:
- Maps characteristics, dimensions, or trends within a population once initial concepts are defined.
- Example: The Voices of Gen Z survey of 3,800 individuals aged 13–28 found 35% dislike reading and 43% read rarely or never.
- Demonstrates correlations between variables without establishing direct causal relationships.
- Explanation:
- Identifies the underlying mechanisms and driving factors behind observed patterns.
- Connects independent variables to dependent variables to account for causal variations.
Explanatory Models: Idiographic vs. Nomothetic
- Idiographic Explanation:
- Focuses on detailed, singular, or small-scale cases to fully explain complex scenarios (e.g., ethnographic study in Chicago recorded in a leader for a day).
- Provides rich, subjective context but cannot be generalized across larger populations.
- Nomothetic Explanation:
- Serves as a standard approach in social science to explain broad patterns across populations using key variables.
- Uses independent variables (e.g., socioeconomic background, education, population density, guinea coefficient) to account for variation in a dependent variable (e.g., regional crime rates in Warner Robins or Atlanta, income levels, emotional openness).
- Example: The power of the weak ties theory demonstrates how wide, superficial social connections provide unique opportunities compared to close ties.
Questions & Discussion
- Topic Specification Example:
- Prompt: Generating specific research questions from a broad topic like abusive romantic relationships.
- Response: A general topic yields multiple specific questions (e.g., target characteristics, post-relationship mental health impacts, survival strategies, or barriers to leaving) requiring distinct methods such as surveys, interviews, observation, or content analysis.
- Correlation vs. Causation:
- Prompt: Evaluating whether classroom engagement directly causes optimism about the future in students.
- Response: Correlation does not equal causation; students optimistic about their future may naturally invest more in education, or engaged students may still feel undecided about their path.
- Student Research Proposals:
- Prompt: Examining sexual abuse reporting in under-supervised organizational structures.
- Response: Combines description and exploration to examine structural factors influencing reported abuse cases.
- Prompt: Investigating how aging out of the foster care system affects long-term economic status.
- Response: Explanatory research linking the mechanism of leaving foster care to socioeconomic status later in life (e.g., studying individuals aged 35–45).
