Document Summary
How to analyze the results of a research study : 1. Identify any measured (dependent) or manipulated (independent) variables. Line graph only when both variables are numbers: 2. True experiment control over iv (created it, assigned groups w/ random assignment); control and manipulate/measure variables; bar or line graphs; used to test a theory. Quasi-experiment two measured variables, treat one as an independent variable; analyze and graph like a true. Quasi-independent variable age (iv but can"t be manipulated); can"t randomly assign people to conditions. Dependent variable extroversion score on test. True correlational study don"t control anything (just ask questions, only have measured/quantitative variables, no manipulated variables, no averages/everyone is an individual); scatter plots; cannot be used to test a theory can"t differentiate cause and effect. How many hours did you study? and what was your grade on the final exam? .
