  2. There were three reasons : ( a ) the cronbach ' s alpha coefficient for raters on the 5 criteria ranged from 0. 83 to 0. 91, which indicated that all the raters shared approximately the consistent rating procedure ; ( b ) in the multivariate generalizability theory ( mgt ), the paradigm got the composite generalizability coefficient of 0. 784, which showed the whole measure of wisdom, relative to each of the 5 criteria, was reliable ; ( c ) the pearson ' s correlation coefficients between the 5 wisdom - related criteria and the 3 positive indicators of psychological well - being ( pwb ) were mostly significant, which indicated that the conception of wisdom did test the knowledge and skills about the real life just like the pwb

    為考察柏林智慧範式的測量信度,研究分別使用經典測量理論和概化理論計算信度指標,結果得到:克朗巴赫系數在0 . 83 - 0 . 91之間,說明智慧的五個特徵維度的評分者一致性都較高;多元概化理論的d研究得出的復合g系數為0 . 784 ,說明智慧測量的整體信度也較高。對于智慧測量的效度,研究選擇具備良好信、效度的心理健康狀況量表(中國修訂版)中的三個指標? ?幸福感、願望與實際所得的符合程度、以及自尊感,作為同時效標。
  3.

    採用x ~ 2檢驗、 pearson積矩相關系數和spearman秩相關系數等方法對濕地植物群落的種間關系研究,結果表明: 36個建群種群和優勢種群構成的630個種對(其中主要是草本植物) ,其中極顯著關聯的種對數分別為49 、 88 、 71 ,顯著關聯的種對數分別是31 、 9 、 7 。
  4. X2 test with 2 2 contingency table and ochiai indices were used to analyze the interspecific association of 12 dominant species of meadow community and 20 dominant species of scrub community and 18 dominant species of tree community. pearson ' s correlation coefficient and spearman ' s rank correlation coefficient were also applied to calculate correlations between species

    在該地區植被的優勢種的種間關系的研究方面,運用2 2列聯表、 x ~ 2檢驗方法對群落優勢種進行總體相關性和種對間的聯結性檢驗,利用共同出現百分率jaccord指數測定種對間的關聯度,應用pearson相關系數和spearman秩相關系數刻畫種對間的數量變化關系。
  5. The results of statistical simulation reveal that intraclass correlation coefficient is a good estimator of reliability, while pearson correlation coefficient over estimates the reliability in many conditions

    統計模擬的結果顯示,組內相關系數是不錯的信度估計量,但皮爾遜相關系數較會有高估的情況。
