The simplest methods of psychology naturally describe the organisms. Checklist, cameras, questionnaires, tape recorders, etc can be used. The case study, survey and naturalistic observations are important descriptive techniques. They are described below:
The psychoanalyst Sigmund Freud discovered this theory from the case study. It is based on the idea that the more we know about individuals, the better we will understand and help them. It can be done at home, school or anywhere.

Advantages
It has larger samples where an investigator with many printed questions ask people to report their behaviour or opinions. Usually mailed, telephoned or directly interviewed. It facilitates to collection of a large amount of data with little effort.
Limitations
Advantages
The collection of data by careful observation of events in their natural settings is called naturalistic observation. It can be done by participating in an event called participatory and it's vice-versa non-participatory. It is called structural observation when the standard, systematic process of reducing the observed information is used properly.
The steps of this concept are as follows:

Correlation is a statistical measure that helps in the prediction of behaviour. Examples; knowing how much aptitude test score correlate with school grades tells us how well the score predict grades in the final exam.
It is a measure that presents between 0 and 1 that indicates a direct relationship meaning that two things together increases or decreases. For example, the amount of violence viewed on TV correlates about 0.3 with aggressive social behaviour.
It indicates an inverse relationship i.e. as one increases, the other decreases thus it is equally predictive. For example, the person who scores low on self-esteem tends to score high on depression as well.
