What is a predictive relationship?
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable (temperature)
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable (temperature)
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable (temperature) predicts another variable
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable (temperature) predicts another variable (ice melting).
Predictive or Arbitrary Relationships
A predictive relationship is a relationship where one variable (temperature) predicts another variable (ice melting).

For example,

For example,
Does stress predict anxiety?
Predictive or Arbitrary Relationships
For example,
Does stress predict anxiety?
Meaning you can tell the amount of anxiety someone has, if you know the amount of stress they are under.

Here are some more examples:
Predictive or Arbitrary Relationships
Administrators wish to know the degree to which the number professor publications in professional journals predicts the time it takes for them to achieve tenure.
Predictive or Arbitrary Relationships
Administrators wish to know the degree to which the number professor publications in professional journals predicts the time it takes for them to achieve tenure.So, if you know the number of professor
publications, you can predict the time it takes to be tenured.

Marine biologist wish to determine the degree to which the levels of nitrogen phosphate concentration predicts a decrease in the number of sea mollusks on the coast of California.

Marine biologist wish to determine the degree to which the levels of nitrogen phosphate concentration predicts a decrease in the number of sea mollusks on the coast of California.So, if you know the levels of nitrogen
phosphate concentration, you can predict the number of Mollusks.

Social scientists wish to determine the extent to which the need for extrinsic motivation predicts the number of selfies taken in a given day.

Social scientists wish to determine the extent to which the need for extrinsic motivation predicts the number of selfies taken in a given day.
So, if you know need for extrinsic motivation, you can predict the number of selfies taken in a given day.
Predictive or Arbitrary Relationships
In such cases, you will classify the relationship as:

In other instances the relationship between two variables is not predictive but arbitrary.

Meaning we do not know what causes what, we just know that:
- when one increases the other increases,
- or when one decreases the other decreases,

When we are not sure which is which, then this becomes an arbitrary relationship as opposed to a predictive relationship.

Note – unless your relationship problem specifies a predictive relationship (with one variable influencing directly another variable) then the problem is most likely arbitrary.
