Explanation:
Correlational research is a non-experimental based research which is used to establish and understand the correlation that exist between two variables statistically.
How to do correlational research
Various process are used to understand correlation between variables , quantitative data is usually useful to understand such relations; which will determine whether there is a weak or strong correlation.
Methods that are used are surveys, observation and archival data.
Surveys
This is a common way to understand if a relationship is there between two variables by conducting questionnaires which can be done through the phone or in person. The question will be related to the two variable of concerns.
The responses can then be evaluated statistically
Naturalistic observation
This is when people or subject are observed in their natural space to see how they behave and analyse the two variables in question without manipulating the subject's environment. The data can then be evaluated quantitatively.
Correlation doesn't mean causation which means one variable is not the cause of the other but their correlation can explain the cause.
Data related to the population can be acquired by the process of collecting, compiling, evaluating, analysing and otherwise disseminating demographic, economic and social data, at a specified time, to all.
The primary sources of the population data on the population size, characteristics and demographic structure are the census, projections, the registrations, migration reports and the surveys.
