A hypothesized causal model has been proposed. How would another researcher go about testing the model?
A) Examine each variable one by one.
B) Identify all paths expressing relationships between concepts.
C) Recruit a small homogenous group to control for most variables.
D) Use a convenience sample to ensure enough subjects.

Question

Quizplus · Accepted Answer

Identifying all paths expressing relationships between the concepts described in the study is critical for model testing for causal relationships. Causal relationship testing necessitates that the connections between the concepts be described and investigated.
The model testing design requires that all variables relevant to the model be measured.
Model testing requires a large, heterogeneous sample to provide a large enough and representative sample required for the study.
Random sampling techniques, rather than convenience sampling techniques, are necessary for this type of study.
