What is the type of design used in descriptive studies that describes the strength and nature of relationships between two variables without clarifying the underlying causes of that relationship is labeled as:A. Cross-sectional design B. Longitudinal design C. Case study designD. Correlational design

The answer is D. Correlational design.

Explanation:

Correlational designs seek to study the relationship between two or more variables in a piece of research. For example, a news article called "Students with healthy diets get better grades at school" is probably based in a correlational study.

It's important to recognise that correlation is not the same as causation. This means: even if two variables appear to be related, that does not indicate a direct cause-effect relationship.

countries such as spain, france and portugal colonized the region. although most of latin america was colonized by spain, the countries of portugal and france also had major influences on the region. due to war and disease, native populations were decimated.
