Because we are observing new cases of disease in a cohort study, what kind of relationship may we establish? Group of answer choices Confounding Temporal Positive Negative Why might there be uncertainty with the association between an exposure and disease in an observational study? Group of answer choices The association may be due to the factors that led people to be exposed (e.g. confounders) rather than the exposure itself. Case-control studies are more valid, so they should be the standard...
From your experimental observations of a series circuit, what relationship do you find between the voltages across the individual resistance and voltage across the entire series group? From your experimental observations of a series circuit, what relationship do you find between the currents through the individual resistance and current through the entire series network? From your experimental observations of a parallel circuit, what relationship do you find between the voltages across the individual resistance and voltage across the entire parallel...
