Response Bias
Bias that occurs when those who respond tend to answer questions in a way that misrepresents the truth consciously (deliberate falsification) or unconsciously (unconscious misrepresentation)
Theory v. Hypothesis & Empirical Testing
- Theory: a formal, logical explanation of some events that include predictions of how things relate. - Hypothesis: A formal statement explaining some outcome -Empirical Testing: Something that has been examined against reality using data
Uncertainty v. Ambiguity
- Uncertainty: descriptive research is conducted to explain the phenomenon, casual research to establish cause-effect relationship -Ambiguity: exploratory research is conducted to clarify the ambiguity
Data Collection
-Asking respondents to fill out a questionnaire -Phone and personal interviews -Asking respondents to taste a product and give their opinions -Observing how much time shoppers spend in front of the product aisle
