# Psychology casual relationship in research

### Causal and non-causal relationships

Causal research, also called explanatory research, is the investigation of ( research into) cause-and-effect relationships. There are often much deeper psychological considerations that even the respondent may not be aware of. There are two. Correlation, causation, and association - What does it all mean??? Correlation - When researchers find a correlation, which can also be called an association. When researchers find a correlation, which can also be called an has a direct influence on the other, this is called a causal relationship.

Tall children tend to be heavier, so high values of X are associated with high values of Y. The correlation coefficient describes the amount of linear association between two such numerical variables. Causal relationships In some data sets, it is possible to conclude that one variable has a direct influence on the other. This is called a causal relationship.

## Association VS. Causal relationships

A scientist in a dairy factory tries four different packaging materials for blocks of cheese and measures their shelf life. The packaging material might influence shelf life, but the shelf life cannot influence the packaging material used.

The relationship is therefore causal. A bank manager is concerned with the number of customers whose accounts are overdrawn. Half of the accounts that become overdrawn in one week are randomly selected and the manager telephones the customer to offer advice.

### Association VS. Causal relationships

Any difference between the mean account balances after two months of the overdrawn accounts that did and did not receive advice can be causally attributed to the phone calls. If two variables are causally related, it is possible to conclude that changes to the explanatory variable, X, will have a direct impact on Y.

Non-causal relationships Not all relationships are causal. Cook and Campbell noted that the concept of inevitability involved in this definition may be inappropriate for the social sciences. Therefore, the authors marshaled a probabilistic concept of causality, that is, a concept where antecedents and consequences are linked probabilistically. This idea has found applications in Steyer's approach to causality.

CRITICAL THINKING - Fundamentals: Correlation and Causation

However, Sobel considers such concepts, and the concepts proposed by Suppes not tenable. Currently, one focus of the discussion of causality in methodology and statistics for a discussion from a philosophical background see, e.

### Statistical Language - Correlation and Causation

Bollen states that if the criteria of isolation, association, and direction are met, variables can be considered causes. However, Bollen also states that human manipulation, a concept currently preferred by many e. Obviously, there is no commonly agreed-upon definition of causality. In the present paper we do not attempt such a definition, nor do we attempt an exhaustive discussion of the philosophical and mathematical intricacies of concepts of causality.

Most important for the present discussion is that we will not operate at the level of variable relationships. Rather, we conceptualize causality at the level of events. We consider events causes of other events.
