The American Sociological Association (ASA) maintains a formal 'Code of Ethics' to ensure that sociological research is conducted with integrity, protecting the rights and welfare of research participants while maintaining professional standards of conduct in the field.

Ethical research practices focus on the protection and well-being of human subjects, including risk assessment, informed consent, data privacy, and anonymity. While selecting a theoretical perspective is a critical part of the research design and academic rigor, it is a methodological or intellectual choice rather than an ethical issue regarding the treatment of participants.

Correlation indicates that two variables change together, but it does not prove that one causes the other. Establishing causation requires meeting specific criteria, such as temporal precedence and the elimination of confounding variables. Relying solely on correlation can lead to false conclusions about the direction or existence of a causal link.

In experimental and correlational research, the independent variable is the factor that is manipulated or changed by the researcher to determine its effect on another variable. Since study time is the input being varied to see if it causes a change in the outcome, it is the independent variable, while the test score is the dependent variable being measured.

A spurious correlation occurs when two variables appear to be causally related but are actually both influenced by a confounding third variable. Recognizing these relationships is crucial in sociological research to avoid drawing false conclusions about direct causation between social phenomena.

In research methodology, an independent variable is the factor that is manipulated or changed by the researcher to observe its effect on another variable. Here, the amount of time spent studying is the independent variable, which is hypothesized to influence the dependent variable, which is the test score.

In research, a correlation describes the statistical association between two variables. When one variable changes as the other changes, they are correlated. This does not necessarily imply causation, but it indicates a measurable relationship where the values of one variable can be associated with the values of the other.

While correlation, association, and connection all describe relationships or links between variables, causation implies a specific directional influence where one variable directly produces an effect in another. In sociology, establishing causation is significantly more rigorous than identifying correlation, as it requires meeting criteria such as temporal precedence, non-spuriousness, and a theoretical mechanism.

To establish causality, researchers typically require correlation, proper time order (cause before effect), and the elimination of spurious variables. While 'theory' provides the framework for the hypothesis, 'internal consistency' is a measure of reliability within a test or scale, not a requirement for establishing a causal link between two distinct variables in a study.

In research, 'association', 'correlation', and 'connection' all describe relationships between variables without necessarily implying that one causes the other. 'Causation' is distinct because it requires a specific causal mechanism where one variable directly produces an effect in another, which is a much stricter and more difficult standard to prove.
