Course Description:

(Health 221) is an introductory level statistics course focus on the intuitive understanding of statistical concepts used in biostatistics. The student will be able to organize, summarize and analyze data numerically and using the statistical package (SPSS).

Evaluation:

The class participation and the homework done during the lectures will be considered. There will be two in-terms exams, each of them will cover a predetermined material. Real data are given to the student and she will be asked to make organization, summarization and analysis using SPSS in the computer lab. Final exam will include all topics covered in the lectures and also some results obtained from analyzing certain data using SPSS to comment on them. The distribution of points one can earn toward a final grade will be as follows:
