Document Summary
A need is a state of tension. Needs create the motivation to behave in a certain way. The magnitude of the tension created by a need is called a drive. Research question: specific questions that elaborate the purpose of your research and address the gap in knowledge. Descriptive: identifies and describes behaviors and the participants. Cannot make predictions or determine causality: focus groups, watching how people interact with some aspect of their environment, can be unobtrusive: watching shoppers in stores, can be very intrusive: watching people in their homes, advantages, disadvantages. Surveys/interviews: each person responds to a preset list of questions, qualitative questions, quantitative questions. Correlational: basic purpose: detect naturally occurring relationships, to determine weather a relationship or association exists, to see how well one variable predicts another. Experimental: can help you avoid some of the pitfalls of correlation all research, experiments can help you isolate the cause of a change in behavior, variables are manipulated, explore cause and effect.
