Answer:
An observational study of an association between two variables.
Explanation:
In the given scenario, it is an observational study of an association between two variables. The variables being :
- Explanatory variable (independant variable / predictor variable) may explain or influence changes in a response variable.
- Response variable (dependant variable) measures an outcome of a study.
Observational study observes individuals and records variables but doesn't attempt to influence the response (does not impose a treatment). It allows the researcher to directly observed the behavior of inteest rather than rely on the subject's self-descriptions (Survey) thus allowing the researcher to study the subject in its natural environment, thus removing the potentiallybased effect of the unnatural laboratory setting on the subject's performance.
Answer:
"contained in"
Explanation:
Just as it is given in the question above, the responsibility of derivative classifiers is to make sure an already classified documents or data is used in the production of a new set of data or documents and this new set of data or document or information must include things or sources from the original classified documents or data.
As simple as ABC, When there is NO need for additional interpretation or analysis in order to get the classification of that information, then the concept we are dealing with is that of "CONTAINED IN".
If there is a need for additional interpretation or analysis in order to get the classification of that information, then the concept we are dealing with is that of "Revealed by".
