2 الترابط العددي في القرآن الكريم ان الاعجاز العددي لايقتصر على التساوي في تكرر الالفاظ.. اذ ان فيه التناسب في الاعداد فمثلا تكرر لفظ الرحمن في القران الكريم 57 مره.. وتكرر لفظ الرحيم 114 مره.. اي ان الرحيم تكرر ضعف الرحمن وتكرر الجزاء 117 مره.. وتكررت المغفره 234 مره.. اي ان المغفره ضعف الجزاء وتكررت الابرار ضعف ماتكررت الفجار.. فبينما ذكرت الاولى ست مرات ذكرت الثانيه ثلاث مرات وتكررت اليسر ثلاث اضعاف ماتكرر العسر.. فقد تكررت اليسر 36 مره في حين العسر 12 مره وكذلك فيه الترابط العددي فنجد ان لفظ قل.. وهو الامر من الله سبحانه وتعالى تكرر 332 مره في القران.. ومجموع الفاظ قالوا من الانس والجن في الحياة الدنيا والاخره 332 مره وايضا نجد ان الشهر قد تكرر 12 مره.. اي بقدر سنه وان اليوم قد تكرر ايضا 365 مره.. اي بقدر سنه 2Fadwa Flemban

4 Non Parametric Tests الاختبارات اللامعلمية عند وجود خلل في أحد الشروط الواجب توفرها لإستخدام اختبارات t نلجأ للاختبارات اللامعلمية. الاختبارات اللامعلمية المناظرة لاختبارات t تكون أقل قوة. 4Fadwa Flemban

5 Non Parametric Tests Fadwa Flemban5

6 Non Parametric Tests One-Sample The Binomial Test Example: random sample was withdrawn for a number of children's weights and were as follows: 35, 25, 15, 20, 30, 24, 35, 15, 25, 30, 32, 33, 34, 16, 19, 20, 31, 10. Required test the hypothesis average weight of the child over than 25 kilos at the confidence interval 99%? Fadwa Flemban6

7 Mathematically solution Fadwa Flemban7 H 0 := 25 H 1: > 25 Use a = 0.01 Compute for the z – statistic. = = 0 from observations the sign= + 0 - - + - + - 0 + + + + - - - + - (It means s = 8, n = 18-2 = 16 ). Compute for the critical region. At a = 0.01, we reject H 0 if z>z 0.01 (z>+2.33). Thus, we don't reject the null hypothesis and conclude that the average weight of the child equal 25 kilos.

9 Fadwa Flemban9 The result: p-value (1-tailed) = 0.815/2= 0.41 a = 0.01 0.41>0.01 don't reject H 0 The result: p-value (1-tailed) = 0.815/2= 0.41 a = 0.01 0.41>0.01 don't reject H 0

10 Non Parametric Tests Two-Independent Samples The Man-Whitney test Fadwa Flemban10 Example: To compare the ratios of intelligence between the two schools A and B, selected a random sample of students from these schools, intelligence test was conducted and the results were: A22192321242018 2422252420 B18201722192321 161820 test the hypothesis that the students in the school A are smarter than the students in the school B at the level 0.05?

Assign the smallest observation the rank 1. If some observations have tied values, assign the rank that is the average of the ranks they would have been assigned if there were no ties. Rank all observations in increasing order from smallest to largest. Assign the smallest observation the rank 1. If some observations have tied values, assign the rank that is the average of the ranks they would have been assigned if there were no ties.

At a = 0.05, we reject H 0 if z>z 0.05 (z>+1.65), from above 2.21 > 1.65 Thus, we reject the null hypothesis and conclude that the students in the school A are smarter than the students in the school B at the level 0.05

15 Output: Fadwa Flemban15 p-value: (1-tailed) = 0.014 a = 0.05, 0.014<0.05 we reject H 0 Students of school A are smarter p-value: (1-tailed) = 0.014 a = 0.05, 0.014<0.05 we reject H 0 Students of school A are smarter

16 Non Parametric Tests Two-Related Samples The Wilcoxon test Fadwa Flemban16 Example : Two people decided correct the answer sheet of 20 students in statistics, were them degrees as follows: A68757987806972 90756723566590 885168574845 B63757285836968 87727021566785 845366524843 Test the hypothesis that the person A gives the degrees different than the person B at the confidence interval 95%?

17 Mathematically solution H 0 : µ1 = µ2 H 1: µ1 > µ2 Use a = 0.05 Compute for the z – statistic. (T =(14+16+3.5+11.5+8.5+8.5+3.5+14+11.5+3.5+14+3.5) =112 ). Compute for the critical region. At a = 0.05, we reject H 0 if z>z 0.05 (z>+1.65). Thus, we reject the null hypothesis and conclude that the person A gives the degrees larger than the person B. Fadwa Flemban17

34 التقرير الاحصائي Fadwa Flemban34

35 كيف تكتبي تقريراً احصائياً ؟ التقرير الاحصائي لابد ان يشمل العناصر التالية : 1- تمهـيد 2- مقدمـة 3- طرق التحليل 4- النتائـج 5- الخلاصـة 6- المراجع 7- الملاحـق Fadwa Flemban35

36 أفضل التقارير الاحصائية هي التي تتسم بـ : البساطة والسهولة في الاجابة عن جميع الأسئلة قيد الدراسة. وصف البيانات وطرق جمعها وتلخيصها إما برسوم بيانية أو جداول أو غيرها. جعل الهدف هو تزويد القارئ بمعلومات كافية عن البيانات. وصف ومناقشة الشكل البياني أثناء التقرير. مراعاة المهارة اللغوية. الابتعاد عن التراكيب اللغوية المعقدة والحواشي غير الضرورية. لابد من التعليق على كل جدول أو شكل بياني مرفق مع التقرير. Fadwa Flemban36

37 اعلمي ان التقرير سوف يقوّم حسب الخصائص التالية : النسق الاحصائي : مناسبة الطرق الاحصائية المختارة في التحليل وصحة تطبيقها. النسق العلمي : من حيث القيمة العلمية للبحث والنتائج التي توصلت لها. النسق اللغوي : من حيث الكتابة والمنطق والترتيب والوضوح. Fadwa Flemban37
