The trait is further assumed to be measurable on a scale (the mere existence of a test assumes this), typically set to a standard scale with a mean of 0.0 and a standard deviation of 1.0. Unidimensionality should be interpreted as homogeneity, a quality that should be defined or empirically demonstrated in relation to a given purpose or use ...
The first uses of test crosses were in Gregor Mendel’s experiments in plant hybridization. While studying the inheritance of dominant and recessive traits in pea plants, he explains that the “signification” (now termed zygosity) of an individual for a dominant trait is determined by the expression patterns of the following generation.

The anima and animus are a pair of dualistic, Jungian archetypes which form a syzygy, or union of opposing forces. Carl Jung described the animus as the unconscious masculine side of a woman, and the anima as the unconscious feminine side of a man, each transcending the personal psyche. [1]
Therefore, they included questions designed to indicate whether someone wishes to come to conclusions (judgement) or to keep options open (perception). [ 13 ] This personality typology has some aspects of a trait theory: it explains people's behavior in terms of opposite fixed characteristics.
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
The events 1 and 6 are mutually exclusive but not collectively exhaustive. The events "even" (2,4 or 6) and "not-6" (1,2,3,4, or 5) are also collectively exhaustive but not mutually exclusive. In some forms of mutual exclusion only one event can ever occur, whether collectively exhaustive or not.
Trait d'Union (English: "Hyphen") was an organized caucus in the French Socialist Party. Trait d'Union was founded in August 2005 by supporters of Jean-Luc Mélenchon within the New World caucus. Soon afterward, the faction supported Laurent Fabius ' motion at the Le Mans Congress and at the Reims Congress in 2008, it supported Benoît Hamon .
In genetics, a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. [1] All parent organisms must be true breeding to properly carry out such an experiment. In one cross, a male expressing the trait of interest will be crossed with a female not expressing the trait.
