Syllabus in Biostatistics 1 Course Description: Biostatistics is a three-unit course designed to cater students in the health sciences entering the world of scientific inquiry. This course deals with the “how’s” and “why’s” of descriptive and inferential statistics in order to develop in them the skills necessary in making decisions. College Algebra is a pre-requisite of the course. Course Objectives: The students should be able to: 1. develop analytical and logical thinking in utilizing correctly the different kinds of statistical methods 2. construct and test hypotheses that are essential in conducting research in the health profession as an application of statistics 3. display speed and mastery in solving types of problems by themselves and the responsibility in doing and passing their requirements on time 4. show desirable traits such as honesty, cleanliness, cooperation and leadership in attending classroom activities Course Requirements: The students should have regular attendance and must pass quizzes, recitations, assignments, problem sets, and periodical examinations.
