Task 7: Identifying different types of associations Flashcards
what is a causal relationship?
if one variable directly influences the other
can be unidirectional (a->b) or bidirectional (influence each other)
what is a correlational relationship?

=covariataion
def.: corrolational Research
no attempt to manipulate, just observe
def: predictor variable
variable used to predict criterion variable
def.: criterion variable
variable whose value is predicted
def.: third-variable problem
possibility that observed correlational relationship might me caused in third variable
def.: directional problem
even if causality exists, often don’t know which causes effects in which
