Consider two variables x and y.
If x varies directly as y then y = cx where c is some constant of variation. This means that whenever x increases, y increases and it increases by c times as much as the increase in x. Also, if x decreases, then y decreases by c times the decrease in x.
If x varies inversely as y then y = k/x where k is some constant of variation. This means that whenever x increases, y decreases and it decreases by k times as much as the increase in x. Also, if x decreases, then y increases by k times the decrease in x.
Inverse Direct Joint
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
direct
well there are surely two types of variations... anyone by chance happens to know the third kind, please let me know two types of variations- 1] direct variation 2] inverse variation
Inverse.......when ever you have two variables multiplying it is inverse
the relationship between pressure and volume a direct or inverse?
direct
direct means it stays the same while inverse means it will change.
Direct or inverse relationships,that is a problem
direct proportion: y=kx inverse proportion: y=k/x
Both are variations of certain kinds of equations. X=kY is a direct variation since X varies directly as Y and k is the constant of variation. X=k/Y is an inverse variation where X varies inversly as Y and k is the constant of variation. Both of these variations are also functions.
