Question

What are important considerations in evaluating correlational studies?

Answer 1

Correlational study is used to determine the relation between any two variables which are not chosen randomly. Correlational study is a type of non experimental research .There are three types of correlational study namely

• Positive correlation
• Negative correlation
• No correlation

An important consideration in evaluating correlational studies is to select two variables without any influence on them and they are measured statistically. In a correlational study only the relation between the variables (Relative contribution)should be evaluated as it is an initial research helping to explore more about the variables.This study is reliable and valid but it cannot determine the causation variable .A correlation coefficient should be found out which is a statistical measure of the degree ,where there is a change in any one variable ,can estimate the consequence or change going to appear in second variable.Data collected should be appropriate to make the correlational study a success.
