PS295 Lecture Notes - Lecture 2: Seat Belt, Design Of Experiments, Theoretical Definition
Document Summary
Research question--->hyptheses ( answer to your research question)-->theory ( support the hypothesis)---> model. Methodological pluralism---> diff research approaches to study/test a theory,, more support to the hypothesis, increase confidence in the conclusion. Strategy of strong inference--> sometime research test a theory simultaneously testing the. Types of research classified by 4 major types. Descriptive research---> provides foundation for another research, ex demographic info, not done on its own. Correlational research--> 2 variables ( not cause or effect), relationship do the two things change together. Experimental research---> cause and effect, the experiment is manipulating something ( increased stress and heart rate. Quasi experimental design---> can not manipulate the independent variable ( gender, height) can not change gender, ethical reasons ( studying seat belt laws) ( cause and effect), use the same design as an experimental research design. Review what type of research is conducted with the goal of finding solution to immediate problems.
