Let us say that we are considering two quantities which we can call x and y. These could be anything - temperature and pressure, population and crime rate, weight and height, etc. If these have a direct relationship (or a direct correlation as we might also call it) that means that if you increase one, you increase the other, or if you decrease one, you decrease the other. So if x increases, y also increases. If it is an inverse relationship (or correlation) that means that increasing one will decrease the other. If you get more x, you will then have less y.
Note that there is a third alternative. Many things have no relationship, either direct or inverse, so if you increase x, that tells you nothing about what will happen with y. These quantities would be said to have no correlation.

What are two types of mathematical relationships that exist between different variables?
Direct or inverse relationships,that is a problem
The differences between linear relation and inverse relation?
Can you tell me the definitions for these different kinds of relationships in statistics. direct, direct to the nth power, joint, inverse ane regress?
What are the two types of relationships that exist amongst physical quantities?
Direct relationships and inverse relationships. In direct relationships, two physical quantities change in the same direction (e.g., as one increases, the other also increases). In inverse relationships, two physical quantities change in opposite directions (e.g., as one increases, the other decreases).
What is positive inverse or direct?
Direct
Is this an example of direct or inverse proportion?
direct
Is the relationship between pressure and volume direct or inverse?
the relationship between pressure and volume a direct or inverse?
What is the opposite of inverse?
direct
What is the difference between a direct and inverse relationship?
direct means it stays the same while inverse means it will change.
What do you know about direct proportion and inverse proportion?
direct proportion: y=kx inverse proportion: y=k/x
How do you do a direct variation with an inverse variation problem?
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
Differentiate direct proportion from inverse proportion?
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
The relationship between quantity demanded and price is direct or inverse?
direct
