Correlational studies are a type of research often used in psychology as a preliminary way to gather information about a topic or in situations where performing an experiment is not possible the correlational method involves looking at relationships between two or more variables. A correlation coefficient is usually used during a correlational study it varies between +1 and -1 it varies between +1 and -1 a value close to +1 indicates a strong positive correlation while a value close to -1 indicates strong negative correlation.

Correlation can refer to either the statistic used to represent the degree of relation between two variables or to the correlational level of interpretation in research methods the correlation coefficient, often denoted as r , is a statistic that describes how strongly variables are related.
A correlation refer to a relationship between two variables it is a technique of analysing data rather than a research method, often used when it is not possible to do an experiment due to ethical or practical reasons.
