This manual is designed for organizers and teachers concerned with training personnel working at the primary and intermediate levels in government statistical offices. The major content consists of outlines for nine training courses: (1) Principles and methods of statistics; (2) Designing a statistical investigation; (3) Data collection by field work; (4) Data collection from records; (5) Data processing; (6) Presentation and publication of statistics; (7) Utilization of statistics; (8) Supervision of statistical work; and (9) Statistical organization, co-ordination and standards. A timetable is suggested for each course; then, under each topic (26 in all), an elaboration of the subject matter is followed by discussion of the most suitable teaching methods and materials for that topic. It is hoped that use of such sources will eventually lead to an improvement in the statistics available from developing countries. (MM)
