ABOLISHED 12/01/2014 PER PAY LETTER 15-04 - Biostatistician IV

California State Personnel Board Specification

  • Schematic Code: LX90
  • Class Code: 5543
  • Established: 05/10/1962
  • Revised: --
  • Title Changed: --


Under general direction, to do research on theoretical statistical problems arising from public health practices and research; to develop, modify and apply complex mathematical statistical theory to problems in the fields of study design, experimental design, and data processing; to provide consultation to professional personnel on the conceptualization and design of complex investigations amenable to statistical analysis; and to do other related work.

Distinguishing Characteristics

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 unproven 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.

Typical Tasks

Conducts research, develops and applies complex techniques in such areas as sequential analysis, stochastic processes and mathematical model building, as well as in the more conventional areas of statistics; initiates recommendations for use of new statistical techniques; acts as a technical resource for other statistical personnel; reviews research reports for statistical validity and clarity; writes reports; may teach in an in-service training program; may supervise a technical and statistical-clerical staff.

Minimum Qualifications

Experience: Eighteen months of teaching or research experience in biostatistics at the postdoctoral level. and Education: A Doctoral Degree in Biostatistics or a closely related field.

Knowledge and Abilities

Knowledge of: Modern probability and statistical theory and its applications; current statistical research literature; principles, problems and terminology of public health; demography and epidemiology; census and registration systems.


Ability to: Become thoroughly familiar with any specialized area of statistics by independent study; maintain professional relationships with statistical groups in other research organizations; devise feasible, constructive courses of action for the solution of statistical problems; prepare and present research reports; speak and write effectively; explain and interpret complex statistical concepts and procedures.

Special Personal Characteristics

Demonstrated ability to think independently and creatively and to carry out research on statistical problems.
