Answer to Question 1
Responses should consider:
- Correlational research is a scientific research methodology that determines the extent to which two variables are systematically related to each other.
- This type of research is so common in human sexuality research because researchers typically cannot control people's sexual behavior as would be necessary for an experiment.
- Most studies conducted in the field of human sexuality use correlational research because researchers must usually take data that are already associated with their research participants and look for predictive links between them.
- A positive correlation indicates that we can predict that two variables will change together in the same direction. An example is shoe size and height; as one increases, the other does, as well.
- A negative correlation tells us that the variables move predictably in the opposite direction. An example is amount of alcohol consumed and driving ability; as one increases, the other decreases.
- No correlation means that there is no consistent, predictable relationship between two variables, such as the relationship between shoe size and driving ability.
