Statistics and Data Analysis ( الإحصاء وتحليل البيانات)

Welcome to Engineering Statistics and Probability Theory

This course will go over theories and implementation of engineering statistics and probability theories to real business problems. Each section has many examples, quizzes, and assessment exams.

Our course includes professional HD Videos with extensive case studies to show you how to apply this knowledge to solve real and practical problems.

In this course we will cover:
