| Abstract | ||
| استخدمت أربع طرائق لتقدير المشاهدات المفقودة في تصميم القطاعات العشوائية الكاملة، وهي: Yates وHarry وRubin وHaseman and Gaylar. وقد تمت المفاضلة بين هذه الطرائق وفقا للمعايير الإحصائية الآتية: قيمة متوسط مربعات الخطأ (MSe)، ومتوسط مربعات المعاملات (MSt) وقيمة الفرق المعنوي بين المعاملات (cal. F)، مع الأخذ بالاعتبار سهولة إجراء التحاليل الإحصائية. وقد تبين أن أكفأ الطرائق هي طريقة Haseman and Gaylar، تليها طريقة Harry ومن ثم طريقة Yates. وقد عجزت طريقة Rubin من مجارات الطرائق الثلاث الأخرى.Four methods for tackling missing values were presented in randomized complete blocks design: Yates, Harry, Rubin, Haseman and Gaylar. To prefer between these methods some statistical measurements were used: error mean square (MSe), treatments mean square (MSt) and the value of significant differences between treatments (cal. F), with addition to the easiest path of statistical analysis.It was found that the most preferable method was Haseman and Gaylar, followed by Harry method and the last one was Yates method. However, Rubin method has failed to go along with the others. | ||
