[¦kō·ə′fish·ənt əv ‚ā·lē·ə′nā·shən]
(statistics)
A statistic that measures the lack of linear association between two variables; computed by taking the square root of the difference between 1 and the square of the correlation coefficient.

The coefficient of alienation (CA) was low from Table 1, 4 and 5 (range of value = 0.2717-0.4398) but high from Table 6 and 7 (range of value = 0.72580.8001).
The coefficient of alienation (Ca) was low in Table 1 (0.27 or 27%), Table 4 (0.31 or 31%) and Table 5 (0.44 or 44%) but high in Table 6 (0.73 or 73%) and Table 7 (0.80 or 80%).
The slight nonlinearity (flattening for correlations approaching zero, which may reflect the anchoring effects described earlier) suggests that the "best" fit may be something other than a linear function of r - perhaps more closely akin to re or the coefficient of alienation, [1 - [(1 - [r.sup.2]).sup.0.5]], as others have suggested (e.g., Jennings et al., 1982; Lane et al., 1985).
For each judgment modality, correlations between judged correlation strength and each of the following were computed: actual Pearson's r, [r.sup.2], and coefficient of alienation. These correlations are shown in Table 2.
