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:
“Mothers often are too easily intimidated by their children’s negative reactions...When the child cries or is unhappy, the mother reads this as meaning that she is a failure. This is why it is so important for a mother to know...that the process of growing up involves by definition things that her child is not going to like. Her job is not to create a bed of roses, but to help him learn how to pick his way through the thorns.”
—Elaine Heffner (20th century)
“Living in cities is an art, and we need the vocabulary of art, of style, to describe the peculiar relationship between man and material that exists in the continual creative play of urban living. The city as we imagine it, then, soft city of illusion, myth, aspiration, and nightmare, is as real, maybe more real, than the hard city one can locate on maps in statistics, in monographs on urban sociology and demography and architecture.”
—Jonathan Raban (b. 1942)
