The intrinsic components of a test are precisely termed its psychometric properties. First, the theoretical relationships must be specified.
What are ethical considerations in research? If you fail to account for them, you might over- or underestimate the causal relationship between your independent and dependent variablesor even find a causal relationship where none exists. Quasi-experiments have lower internal validity than true experiments, but they often have higher external validity as they can use real-world interventions instead of artificial laboratory settings. They should be identical in all other ways. Herman Ed. What is the difference between confounding variables, independent variables and dependent variables?
