It is a positive relationship.
direct variation or positive correlation.
The other can increase, decrease or stay the same. It depends on the relationship between the two variables.
An arithmetic sequence does not have a constant rate of increase or decrease between successive terms, so it cannot be called anything!The constant increase or decrease is called the common difference.
If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.
There is quite a high degree of linear agreement between the two variables with one showing an increase when the other shows a decrease.
Direct variation
Variation in direct proportion.
The two quantities are porportional.
If they increase or decrease exactly, then the constant of proportionality or coefficient of proportionality. If not exactly, then a correlation coefficient.
direct variation or positive correlation.
when ductility increase hardness decrease
by their increase or decrease
They are inverly related ,number increase cost decrease as wellas cost increase may qulity & number decrease
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
The other can increase, decrease or stay the same. It depends on the relationship between the two variables.
It implies that an increase in x is accompanied by an increase in y. And similarly, they decrease together.
Rotation and supination do not increase or decrease the angle between bones.
