Description
COM 225 Lecture – 1/30/14  Introduction to Definitions Variable: something that varies (weather, temperature, personality, etc.)  ­levels of variables: the different values that the variable can take on (the way that  it varies)  Construct: (synonym for variable) typically used when talking about theories Operationalization: the process of measuring a variable (e.g., questionnaire, observe &  collect data w/ scale)  Independent Variable: the “cause” of the relationship  Dependent Variable: the “effect” of the relationship (from the IV)  *can only be definitively named when talking about 2 variables at once – otherwise  context makes it ambiguous  Box & Arrow Models:  Verbal Aggression  ­ >  Physical Aggression  ­arrow signifies the word “causes” in this scenario  ­relationships between variables: how the variable change or cause change in relation to  the other (*which way you draw the arrow determines which you are claiming is the IV)  Positive Relationship: if one variable goes up, so does the other (positive correlation);  variables change in the same direction  Negative Relationship: if one variable goes up, the other goes down (negative  correlation); variables change in opposite directions / they vary inversely  (*see pictures of graphs)  Nominal Variables: have no definite correlation – categories  (e.g., inverted U graph­ nonlinear relationship)  direct relationship: independent variable directly influences the DV indirect relationship: independent variable indirectly influences dependent variable  (through mediators) Spurious relationship: the observed relationship is not due to the cause of the variables  on each other, but rather by a third, shared variable common to both (e.g., verbal aggression not causing physical aggression in this scenario, but rather  the quality of the relationship is causing both) theory: a set of constructs, definitions, and propositions that present a systematic view of  phenomena by specifying relations among variables for the purpose of explaining,  describing, and predicting phenomena  What is Interpersonal Communication?  4 Main Components:  ­number, situation, function (reason/purpose), and development (the stage that the  relationship is in) Nonve
