Then, Cronbach s alpha reliability coefficients were calculated for each scale.
2.
The average internal reliability coefficients across ages 15 17 for the PASS scales are:
3.
The alpha reliability coefficients for these scales run from . 74 to . 98.
4.
Results obtained by different investigators show that the reliability coefficients for memory span are quite high.
5.
Of course, one does not want to inflate reliability coefficients by simply adding redundant items.
6.
The internal consistency reliability coefficient for core and supplementary subtests demonstrate the KABC-II has good reliability.
7.
Expressed in terms of Classical test theory, the correlation is divided by the geometric mean of the reliability coefficients of two tests.
8.
The reliability coefficient \ rho _ { xx'} provides an index of the relative influence of true and error scores on attained test scores.
9.
In its general form, the reliability coefficient is defined as the ratio of " true score " variance to the total variance of test scores.
10.
The DHP-18 has demonstrated very good measurement properties including reliability coefficient > 0.70 and the ability to discriminate between different treatment and patient groups.
