What is Research Design ?g
Definition :• Is a plan for selecting the sources and p g
types of information used to answer the research questionresearch question.
• Is a framework for specifying the relationship among the st d ’s ariablesrelationship among the study’s variables.
• Is a blueprint that outlines each procedure from the hypotheses to analysis of data.

The Scope of Qualitative Researchp
• In depth interviewing (usually conversational rather than structured)• In-depth interviewing (usually conversational rather than structured).• Participants observation (to perceive firsthand what participants in the setting experience).• Films, photographs, and videotape (to capture the life of the group under study).• Projective techniques and psychological testing (such as a Thematic Apperception Test, projective measures, games, or role-playing).• Case studies (for an in-depth contextual analysis of a few events or conditions).• Street ethnography (to discover how a cultural subgroup describes and structures its g p y ( g pworld at the street level).• Elite or expert interviewing (for information from influential or well-informed people in an organization or community).• Document analysis (to evaluate historical or contemporary confidential or public y ( p y precords, reports, government documents, and opinions).• Proxemics and kinesics (to study the use of space and body motion communication, respectively).

Causal Relationships (cont.)p ( )
A t i l l ti hi i i hi h t• A symmetrical relationship is one in which two variables fluctuate together but we assume the changes in neither variable are due to changes in the other.g
• A reciprocal relationship exists when two variables mutually influence or reinforce each other.
• Most research analysts look for asymmetrical relationships. With these we postulate that changes in one variable (the independent variable or IV) areone variable (the independent variable, or IV) are responsible for changes in another variable (the dependent variable, or DV).
