Under close supervision, to assist in the application of mathematical-statistical theory in evaluating complex statistical programs; to assist in the development of new statistical methodology; and to do other related work.
Positions in the research analyst classes are primarily concerned with the use of statistical data in the investigation and analysis of specific subject fields. Positions in the statistical series of classes are primarily concerned with the development of collection and reporting procedures and the statistical analysis of data.
Positions in the Statistical Methods Analyst series are distinguished from other research and statistical classes by the strong emphasis on mathematical-statistical skills. Positions in these classes require knowledge of such mathematical methods as calculus and matrix algebra, and of such statistical theory as estimation, hypothesis testing, sampling, multivariate regression and correlation, and the design of statistical studies utilizing such theories.
Assists in the analysis and development or modification of mathematical-statistical techniques in such areas as sampling design, data collection procedures, the significance testing of means with equal or unequal numbers of observations, probability calculations, confidence interval estimation, and least-square multiple variable regression analysis; makes complex statistical calculations using conventional computing equipment; prepares charts, tables, and reports which explain or demonstrate the results of development of evaluation of statistical methods.
Education: Equivalent to graduation from college with a major in statistics or other applied science area which has included or been supplemented by a minimum of 12 semester hours of progressively more difficult courses in statistics and 12 semester hours of college- level mathematics, including a course in calculus. (Technical experience requiring the use of mathematical-statistical theory may be substituted for the required education on a year-for-year basis.) (Registration as a senior will admit applicants to the examination but they will be required to submit written proof of graduation before they may be appointed.)
Knowledge of: Statistical theory and methods including sampling, analysis of variance and covariance, probability theory, correlation and regression, confidence interval estimation, and testing of hypothesis; mathematical theory and methods including integral and differential calculus and theory of determinants and matrix algebra; procedures of collecting and processing statistical data; operation of office equipment used in statistical analysis of data.
Ability to: Prepare clear and concise reports; analyze data; present statistical data in graphic and tabular forms.
