### What are the 3 correlation conditions?

### Why is correlation important?

Correlation is very important in the field of Psychology and Education as a measure of relationship between test scores and other measures of performance. With the help of correlation, it is possible to have a correct idea of the working capacity of a person.

**Is a correlation evidence?**

The assumption that A causes B simply because A correlates with B is often not accepted as a legitimate form of argument.

## What is the importance of correlational?

Conclusion: Findings from correlational research can be used to determine prevalence and relationships among variables, and to forecast events from current data and knowledge. In spite of its many uses, prudence is required when using the methodology and analysing data.

## What are the advantages of correlational research?

Another benefit of correlational research is that it opens up a great deal of further research to other scholars. It allows researchers to determine the strength and direction of a relationship so that later studies can narrow the findings down and, if possible, determine causation experimentally.
