    Course Title : Epidemiology and Biostatistics

    Credit Hours : 3 Credit Hours

    Calendar Description : 8 weeks/ Summer Semester - 2nd year

    Teaching Approaches : 4 (90 min) Lectures per week for 8 weeks and field work and report

  • General course description:

    This course provides students with core skills in epidemiology and biostatistics. This course covers analytical and descriptive epidemiology, the epidemiology of infectious and chronic diseases; transmission of infectious diseases, descriptive statistics, the theory of probabilities, levels of significance, hypothesis testing, regression and correlation and the use of statistics in epidemiology.

    Course General Objective:

    To teach students of how to apply their core skills in epidemiology and biostatistics in the field.

  • Method of Instruction : Lectures, practice and field work

    Evaluation and Grading : Two written exams (MCQ) plus one field work and report.

    The students course grade will be primarily determined by a combination of midterm examination, class participation and field work and project, multiple choice style final examination. The final examination will incorporate principles and materials from the required readings and from classroom discussions and lectures.

    Field work and report = 10% Midterm Examination - (written) = 40%

    Final Examination (written) = 50%
