Describe the data for a correlation research study and explain how these data are different from the data obtained in experimental and nonexperimental studies, which also evaluate relationships between two variables.

To determine

To Describe: Type of data for a correlation study.

To find: How correlation study data are different from the data obtained in experimental and non experimental studies.

Explanation

Justification:

Correlational research is a kind of study in which we want to know statistical relationship between the two variables.

The two ways classified paired data is used where observations for both the variables are taken for each of the individual. In correlational study, we want to measure the degree of relationship between two variables. There is no independent variable to manipulate. So, terms independent variable and dependent variable do not apply to this kind of approach.

In experimental study research, dependent and independent terminology is used. The variable which is manipulated by the experimenter is called independent variable and the variable which is observed by the experimenter is called dependent variable. So, only one variable is measured in co-relational study which is different from correlational; study in which both variable is measured...
