الدورة تتناول مفاهيم أساسية في مجال التحليل الإحصائي وتقدم تعريفات وتفاصيل حول كل مصطلح. إليك شرح لكل مصطلح:

1. **Statistical Analysis (تحليل إحصائي):**

- تشير إلى عملية تحليل البيانات باستخدام الأساليب والتقنيات الإحصائية.

2. **Descriptive Statistics (الإحصائيات الوصفية):**

- تشمل الأساليب والتقنيات التي تساعد في تلخيص وتوضيح البيانات بشكل مختصر وواضح.

3. **Inferential Statistics (الإحصاء التستنبطي):**

- يشير إلى الأساليب التي تسمح بالاستنتاجات والتنبؤات حول السكان باستخدام عينة محددة منه.

4. **Hypothesis Testing (اختبار الفرضيات):**

- تقنية إحصائية تستخدم للتحقق من صحة أو عدم صحة فرضيات معينة استنادًا إلى البيانات والتحليل الإحصائي.

5. **Regression Analysis (تحليل الانحدار):**

- تقنية إحصائية تستخدم لفهم العلاقة بين متغير واحد أو أكثر وتأثيرهم على متغير آخر.

6. **ANOVA (Analysis of Variance) (تحليل التباين):**

- تحليل يستخدم لقياس الفروق في المتوسطات بين مجموعات متعددة.

7. **Chi-Square Test (اختبار كاي-مربع):**

- اختبار إحصائي يستخدم لتحليل العلاقة بين متغيرين يحتويان على متغيرات تصنيفية.

8. **Correlation Analysis (تحليل الارتباط):**

- تقنية تستخدم لقياس قوة العلاقة بين متغيرين.

9. **Mean, Median, Mode (المتوسط، الوسيط، الوضع):**

- تشير إلى مقاييس مختلفة لتمثيل المركز الاحتمالي لمجموعة من البيانات.

10. **Standard Deviation (الانحراف المعياري):**

- يقيس مدى تشتت البيانات حول المتوسط الحسابي.

11. **Confidence Interval (فترة الثقة):**

- نطاق يحدد القيم التي يمكن أن تشمل المتوسط الإحتمالي لمتغير معين بثقة معينة.

12. **Normal Distribution (التوزيع الطبيعي):**

- توزيع احتمالي يتميز بأن معظم القيم تتجمع حول متوسطه.

13. **Sample Size (حجم العينة):**

- عدد الوحدات (أفراد أو عناصر) في العينة المدروسة.

14. **Outlier (قيمة متطرفة):**
