Negative relationship
Encyclopedia
In statistics
, a relationship between two variables is negative if the slope
in a corresponding graph is negative, or—what is in some contexts equivalent—if the correlation
between them is negative. Negative correlation is also variously called anti-correlation or indirect correlation.
Example:
"They observed a negative relationship between illness and vaccination."
As incident of vaccination is increasing, incidence of illness is decreasing, and vice versa.
Compare to a positive relationship:
Observed a positive relationship between illness and missed work.
As incidence of illness increased, sick days taken also increased.
