Pearson correlation coefficient

correlation coefficientcorrelationPearson correlation
Negative correlation can be seen geometrically when two normalized random vectors are viewed as points on a sphere, and the correlation between them is the cosine of the arc of separation of the points on the sphere.
The correlation coefficient is negative (anti-correlation) if X i and Y i tend to lie on opposite sides of their respective means.

A negative relationship between two variables usually implies that the correlation between them is negative, or — what is in some contexts equivalent — that the slope in a corresponding graph is negative.

An example would be a negative cross-sectional relationship between illness and vaccination, if it is observed that where the incidence of one is higher than average, the incidence of the other tends to be lower than average.

Time series

Similarly, there would be a negative temporal relationship between illness and vaccination if it is observed in one location that times with a higher-than-average incidence of one tend to coincide with a lower-than-average incidence of the other.

Law of demand

demand theoryif the price was right
In microeconomics, the law of demand states that, "conditional on all else being equal, as the price of a good increases, quantity demanded decreases ; conversely, as the price of a good decreases, quantity demanded increases ". In other words, the law of demand describes an inverse relationship between price and quantity demanded of a good.

Baldwin effect (astronomy)

The Baldwin effect in astronomy describes a relationship between continuum and emission-line fluxes observed in the electromagnetic spectra of quasars and active galactic nuclei, namely an anticorrelation between the equivalent width, W λ, of a spectral line and the continuum luminosity, L, in broad UV optical emission lines.
