observational studies
Observational studies observe natural phenomena without intervention, while experimental studies manipulate variables to determine cause and effect. Observational studies are useful for understanding associations, while experimental studies can establish causal relationships between variables. Experimental studies involve random assignment of participants to groups, while observational studies rely on natural groupings.

those biasthat have or can be accurately measured in observational study, are called overt biases
Apex: Most social studies sources contain bias
bias is the set of preferences or prejudices a writer has about a subject
The main possible advantage is that in an experiment, it is possible to control some of the variables so that it is easier to measure the effect of key variables. In observational studies, no such control is possible.
Observational studies
Bias occurs when a writer intentionally omits information that weakens his or her argument.
situational bias is the tendency of media to focus on one type of story
constellations of covariates may reflect poor model fit in regression modeling using observational studies.
Observational research is where the researcher just observes the ongoing behavior of a subject. Archival studies is where the person goes out and interacts with the subjects and their behaviors.
