Under general direction, to develop and apply mathematical statistical theory to problems in the fields of study design, experimental design, and data analysis; to provide consultation to statistical staff; and to do other related work.
Positions in the class Biostatistician II will be applying standard biostatistical and mathematical statistical techniques to public health data. Originality is required in the problem definition and planning processes, in the selection and minor modification of techniques and in the establishment of sequencing and procedure.
Positions in the class Biostatistician III will be performing work of a more complex nature involving the adaptation or modification of basic aspects of existing biostatistical techniques to specific research problems in public health. Available guidelines may contain inconsistencies or suggest several different approaches to the problem at hand. The incumbent must select and adapt techniques best suited to the immediate problem.
Positions in the class Biostatistician IV will be performing basic research in biostatistical theory, involving the extension of principles, determination of corollary principles, investigation into unknown or unproved principles and synthesis of biostatistical knowledge to develop new techniques for the solution of problems presenting novel or unprecedented aspects. In terms of complexity, problems are difficult to define, require unconventional approaches and available guides and precedents are limited in usefulness.
Reviews problems and develops techniques, or modifies conventional statistical techniques to meet the requirements of the data involved; applies principles of experimental design to the planning of complex studies; prepares research reports and publications; reviews such reports for statistical validity; reviews current relevant statistical literature for techniques applicable to public health problems; recommends on the appropriateness of various modes of data processing in given problems; provides technical consultation to other statistical personnel in the solution of complex problems, and may supervise other statisticians as required.
One year of experience in the California state service performing the duties of a Biostatistician II.
Experience: Two years of experience in the application of biostatistical or related techniques to public health data (a Doctoral Degree in Biostatistics or a closely related field may be substituted for the required experience); and
Education: The degree of Master of Arts or Master of Science in Biostatistics or the equivalent, which shall have included at least twelve units of statistics at the graduate level for which calculus is a prerequisite.
Knowledge of: Theoretical basis for tests of the general linear hypothesis and for regression analysis; nonparametric procedures, sequential analysis, and experimental design; probability theory and stochastic processes; capabilities and limitations of tabulating and calculating equipment and large scale data processing equipment; demography and epidemiology; principles, problems; and terminology of public health; department's Affirmative Action Program objectives; a manager's role in the Affirmative Action Program and the processes available to meet affirmative action objectives.
Ability to: Comprehend current literature in statistics and modify and apply new techniques from the literature; explain statistical concepts to other statistical personnel and interpret them to nonstatisticians; speak and write effectively; maintain cooperative and tactful working relationships with other personnel; effectively contribute to the department's affirmative action objectives.
