SERIES CONCEPT
Statisticians perform professional statistical work Using a
variety of standard statistical methods and programming
techniques in order to complete assignments; and perform other
related duties as required.
Incumbents typically select appropriate test formulas and perform
standard computations such as multiple and partial correlation
coefficients, t-tests, Chi-square, nonparametic tests, and
analysis of variance working from written or verbal instructions;
prepare control cards to adopt particular computer programs for
selected research problems, which may include such factors as n-
way analysis of variance, analysis for unbalanced design,
discriminant analysis and step-wise regression; perform
complicated computations independently on research problems such
as regression analysis, analysis of covariance where the design
is not complex and the mathematical model is relatively simple;
participate in meetings with departmental representatives for the
purpose of modifying codes, designing and changing forms, and
making reports during selected long-term projects; and are
assigned responsibility for the processing of precoded data and
the preparation of related reports.
Incumbents may supervise the work of lower level statisticians
and related personnel in the performance of coding and data
collecting duties; may be assigned responsibility for
recommending specific revisions in statistical codes, requiring
library research and consultation with subject-matter
specialists; may set up specifications for computer programming
problems as required; may develop data screening programs for
computer application using FORTRA.N, PL/l, ALGOL or other
compatible programming languages; may instruct lower level
statisticians and related personnel on the techniques of coding,
statistical computations and utilization of equipment; may do
computations involving new techniques which have been pretested;
and may develop cost estimates as required.
The Statistician series consists of four levels with the
distinction between levels based on the scope and complexity of
statistical functions and the degree of involvement in program
planning.
CLASS CONCEPTS
Principal Statistician
Under direction incumbents are assigned responsibility for
program planning and/or for consultation and analysis requiring
advanced knowledge and significant methodological innovation; and
perform other related duties as required.
Incumbents may direct the activities of a statistical unit which
typically involve performance of functions such as determination
of staff and budget needs, making of staff work assignments, and
development of effective evaluation procedures, and training and
supervision of unit employees. Incumbents assist in planning
research designs on complicated problems or large-scale studies
which may result in contracts or grants, and make job cost
estimates; determine from discussions the purposes and objectives
of various studies, the previous research done on problems, the
scope, methods of approach to problems, and the restrictions
inherent in experiments; make recommendations regarding Possible
alternative approaches or modifications of scope or objectives in
order to develop effective research plans; meet with
investigators to discuss possible statistical analyses of their
research data; interpret results to investigators after
completion of staff analys.is; and meet with principal
investigators, consultants, representatives from granting
agencies as necessary to establish overall policies and
procedures relating to selected projects.
Incumbents may perform statistical consultation and analysis
requiring advanced and current knowledge of statistical theory
and the ability to develop new methodology to meet novel
requirements. Examples of such activity include development of
statistical models in new areas of application and derivation of
inference procedures using maximum likelihood, Bayesian or other
principles; and specification of usage of new statistical methods
with appropriate attention to tests of assumptions, numerical
accuracy and correct interpretation of results.
Senior Statistician
Under direction, incumbents perform complex professional
statistical work and inaddition may supervise lower level
statisticians and related personnel; and perform other related
duties as required.
Incumbents typically spend a majority of time working on one or
more of the following tasks, such as adaptation of mathematical
statistical models for novel analyses of technical data,
independent consultation with department representatives and
principal investigators, and planning and implementation of major
study projects; advise principal investigators on appropriate
experimental designs and statistical tests in order that valid
conclusions can be obtained; plan statistical analysis for
research projects where designs are made complex by the numbers
and kinds of variable number of levels of variables and/or
interactions or relationships between variables consult with
researchers to derive understanding of the hypotheses and
experimental approaches; decide appropriate statistical analyses
for balanced and unbalanced designs; develop mathematical models;
determine feasibility of using electronic computers for
computations; and select or write appropriate computer programs
as necessary.
Incumbents may participate in planning meetings with
representatives of cooperating institutions for purposes of
relating medical and statistical aspects to resolve problems; may
make job cost estimates on statistical analyses which require
consultation with principal investigators; and may try out new
statistical tests which are adaptations of accepted theories
and/or principles of inference.
Statistician
Under general supervision incumbents perform professional
statistical work as outlined in the Series Concept. This is the
operational level of the series.
Assistant Statistician
Under supervision incumbents perform professional statistical
work on a variety of problems typically restricted in difficulty
and scope. Incumbents perform the majority of duties described in
the Series Concept within established procedural guidelines. As
examples of duties assigned to this level, incumbents perform
routine statistical computations such as multiple and partial
Correlation coefficients, t-tests, Chi-square and one-way
analysis of variance; perform complex computations when formulas
are setup and when specific instructions are given in their use;
code raw data and design simple codes for machine processing;
recode data combining and modifying categories; and plot curves
from computer output and prepare final graphs for reports. This
is the entry level in the professional series, however, positions
may be assigned to this level on a continuing basis.
