تهدف هذه الدراسة إلى معرفة الفرق في التحصيل الدراسي في الكيمياء والاتجاه نحو العلوم بين طلاب التخصص العلمي وطلاب التخصص الصناعي الصف الأول كلية التربية ابن الهيثم، كذلك تهدف الدراسة إلى معرفة العلاقة بين التحصيل الدراسي في الكيمياء ودرجات اختبار نهاية الفصل في الكيمياء، والمعدل التراكمي بعد أخذ المقرر الدراسي والاتجاه نحو العلوم بالنسبة لطلاب التخصص العلمي وطلاب التخصص الصناعي.

لقد استخدمت الباحثة اختبار التحصيل في الكيمياء، وكذلك مقياس الاتجاه نحو العلوم لغرض هذه الدراسة، وقد تكونت عينة الدراسة من 36 طالباً من التخصص العلمي، وكذلك 36 طالباً من التخصص الصناعي.

وقد بيّنت نتائج الدراسة ما يلي:-

  • هناك فرق دال إحصائياً عند مستوى دلالة (0.05) بين طلاب التخصص العلمي وطلاب التخصص الصناعي في التحصيل الدراسي في الكيمياء لصالح طلاب التخصص الصناعي.
  • ليس هناك فرق دال إحصائياً في الاتجاه نحو العلوم بين طلاب التخصص العلمي وطلاب التخصص الصناعي.
  • هناك فرق دال إحصائياً عند مستوى دلالة (0.01) في درجات نهاية المقرر الدراسي في الكيمياء بين طلاب التخصص العلمي وطلاب التخصص الصناعي لصالح طلاب التخصص العلمي.
  • هناك معامل ارتباط دال إحصائياً عند مستوى دلالة (0.05) بين التحصيل في الكيمياء Gain Scores ودرجات اختبار نهاية المقرر الدراسي في الكيمياء بالنسبة لطلاب التخصص العلمي.
  • هناك معامل ارتباط دال إحصائياً عند مستوى دلالة (0.01) بين درجات نهاية المقرر الدراسي والمعدل التراكمي بالنسبة لطلاب التخصص العلمي.
  • هناك معامل ارتباط إحصائياً عند مستوى دلالة (0.01) بين المعدل التراكمي والاتجاه نحو العلوم بالنسبة لطلاب التخصص العلمي.

Comparison of Some Methods for Estimating Nonparametric Binary Logistic Regression
...Show More Authors

In this research, the methods of Kernel estimator (nonparametric density estimator) were relied upon in estimating the two-response logistic regression, where the comparison was used between the method of Nadaraya-Watson and the method of Local Scoring algorithm, and optimal Smoothing parameter λ was estimated by the methods of Cross-validation and generalized Cross-validation, bandwidth optimal λ has a clear effect in the estimation process. It also has a key role in smoothing the curve as it approaches the real curve, and the goal of using the Kernel estimator is to modify the observations so that we can obtain estimators with characteristics close to the properties of real parameters, and based on medical data for patients with chro

Linear discriminant analysis and logistic regression are the most widely used in multivariate statistical methods for analysis of data with categorical outcome variables .Both of them are appropriate for the development of linear  classification models .linear discriminant analysis has been that the data of explanatory variables must be distributed multivariate normal distribution. While logistic regression no assumptions on the distribution of the explanatory data. Hence ,It is assumed that logistic regression is the more flexible and more robust method in case of violations of these assumptions.

In this paper we have been focus for the comparison between three forms for classification data belongs
