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.
Direct or inverse relationships,that is a problem
Can you tell me the definitions for these different kinds of relationships in statistics. direct, direct to the nth power, joint, inverse ane regress?
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).
Direct
direct
the relationship between pressure and volume a direct or inverse?
direct
direct means it stays the same while inverse means it will change.
direct proportion: y=kx inverse proportion: y=k/x
direct
If a variable X is in inverse variation with a variable Y, then it is in direct variation with the variable (1/Y).
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
