Researchers who are interested in the relationship between televised aggression and subsequent behavior have found that children who watch a good deal of televised aggression (murders, crime shows, shootings, etc.) tend to be more aggressive than those who watch little of this type of television programming. This is an example of a(n) study.

Correlational Study

Explanation:

A sociologist may also conduct correlational research. A correlation is a relationship between two variables (or “factors that change”). These factors can be characteristics, attitudes, behaviors, or events. Correlational research attempts to determine if a relationship exists between the two variables, and the degree of that relationship.

A social researcher can use case studies, surveys, interviews, and observational research to discover correlations. Correlations are either positive (to +1.0), negative (to −1.0), or nonexistent (0.0). In a positive correlation, the values of the variables increase or decrease (“co‐vary”) together. In a negative correlation, one variable increases as the other decreases. In a nonexistent correlation, no relationship exists between the variables.

People commonly confuse correlation with causation. Correlational data do not indicate cause‐and‐effect relationships. When a correlation exists, changes in the value of one variable reflect changes in the value of the other. The correlation does not imply that one variable causes the other, only that both variables somehow relate to one another.
