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.
Famous quotes containing the words negative and/or relationship:
“The negative cautions of science are never popular. If the experimentalist would not commit himself, the social philosopher, the preacher, and the pedagogue tried the harder to give a short- cut answer.”
—Margaret Mead (1901–1978)
“The relationship between mother and professional has not been a partnership in which both work together on behalf of the child, in which the expert helps the mother achieve her own goals for her child. Instead, professionals often behave as if they alone are advocates for the child; as if they are the guardians of the child’s needs; as if the mother left to her own devices will surely damage the child and only the professional can rescue him.”
—Elaine Heffner (20th century)
