Validity coefficients will always be _____ in the original sample compared to a second sample used for cross-validation.

Question

Quizplus · Accepted Answer

Validity coefficients are typically higher in the original sample because the measures are specifically developed or tailored for that group, leading to an overestimation of their predictive power. When applied to a second, different sample for cross-validation, the coefficients often decrease, reflecting a more accurate estimate of their true predictive validity across different populations.
