However , a much different conclusion was reached when the validity coefficients were tested statistically 然而,当测试统计有效系数时,会得出大相径庭的结果。
We have got relatively ideal reliability and validity coefficient in probing the coordinating ability , the decision - making ability and the writing ability 而在测查协调能力、决策能力、书面表达能力也取得了较为理想的效果。
No significant differences were found for the validity of the ability tests , and when peer ratings were used as predictors , only 16 out of 84 pairs of validity coefficients showed a statistically significant fifference 能力测试的有效性并无显著差异,当同等级别被设置为预报器时,在84对有效系数之外,仅有16对有效系数显示差异显著。
