Biostatistics Introduction This lecture note is prepared primarily for the health extension workers who need to know the basic principles of data collection and presentation. It is also hoped that it will serve as an additional reference material for the instructor of the health extension students. While preparing this lecture note, care was taken not to go beyond the level of the health extension students. However, by taking account of the shortage of reference material of this sort, a few topics which may seem a little bit difficult for the students were added to assist their biostatistics instructors. To make things easy and to facilitate the teaching/learning process, a detailed explanation is given throughout the lecture note. The first unit deals with the basic concepts and definitions of statistics in general and health service statistics in particular. Units two and three cover the methods of data collection and presentation. Unit four focuses on demographic methods with greater emphasis given to censuses and vital statistics. A relatively comprehensive description of measures of central tendency and variation is given in unit five. General learning objectives followed by introductory sections are given at the beginning of each unit. Each unit has a number of 1
Biostatistics questions, most of them based on real data. A few reference materials are given at the end of the lecture note for further reading. 2
