What is the goal of a multivariate correlational study? - Answer To examine
associations involving three or more measured variables and improve internal
validity.
What are the three causal criteria in multivariate correlations? - Answer 1.
Temporal precedence, 2. Covariance, 3. Internal validity.
What is temporal precedence? - Answer The causal variable must occur before
the effect variable in a causal relationship.
What does internal validity refer to? - Answer The extent to which a study can
rule out alternative explanations for the relationship between variables.
What is a confound in research? - Answer A third variable that may influence
the relationship between the independent and dependent variables.
What is a criterion variable in multivariate regression? - Answer The dependent
variable that the study aims to predict or explain.
, What is a predictor variable in multivariate regression? - Answer The
independent variables that are used to predict the criterion variable.
How does beta differ from r in regression analysis? - Answer Beta indicates the
strength and direction of the relationship while controlling for other variables,
unlike r which shows correlation without control.
What is the significance of cross-lag correlation in longitudinal studies? - Answer
It helps establish temporal precedence by examining the relationship between
variables over time.
What is the role of code books in research? - Answer They train naive observers
on what to look for in data collection to minimize bias.
What is reactivity in the context of observational studies? - Answer When
participants alter their behavior because they are aware they are being observed.
What is the impact of a knowledgeable observer on data collection? - Answer
They may collect biased data due to their expectations influencing what they
observe.
What is the relationship between sample size and statistical validity? - Answer
Larger samples improve statistical validity but do not necessarily enhance
external validity.
