The George W. Snedecor Award honors an individual who was instrumental in the development of statistical theory in biometry. Dr. Snedecor was a pioneer in improving the quality of scientific methods concerning the use of statistical methodology. He spent his career at Iowa State University (ISU), becoming the first director of the Statistical Laboratory in 1933. He worked in experimental design, sampling, and was instrumental in the use of statistical methods. His book, Statistical Methods, went to seven editions and was translated into nine languages. The award is for a noteworthy publication in biometry within three years of the date of the award. The Snedecor Award was established in 1976 and is awarded bi-annually.
The Award Committee selecting the recipient will consist of six members, one member appointed by each of the five COPSS member societies and one member appointed by the Chair of COPSS. The appointment terms for these six members are for two cycles of the award, normally four years. The award winner from 6 years previous to the current award is invited by the COPSS Chair to serve as the seventh committee member. His/her term is for two years. The Chair of the Award Committee will be selected by the Chair of COPSS from among the members of the current Award Committee.
Frequency of Award
The award shall be given every other year (biennially) if, in the opinion of the Award Committee, an eligible and worthy nominee is found. The Award Committee shall have the option of not giving an award for any given year. The Award Committee may not split the award, but if the winning paper is a paper, then the award acknowledges all the authors of that paper.
Nominations and Eligibility
The award is open to all regardless of age, race, gender, sexual orientation, nationality or citizenship. Nominees must be living at the time of their nomination. Nomination submissions will be invited by October and close on December 15th of the previous year in which the award is to be made. Nominations may be made by members of any of the COPSS affiliated organizations. Prior nomination does not exclude a nominee from consideration in subsequent years. No member of the Award Committee, of COPSS, or societal member of COPSS shall be eligible to receive the award during his or her term of service
Eligible candidates are expected to adhere to the highest standards of statistical practice, professional conduct, and personal conduct; see the Ethical Guidelines for Statistical Practice published by the Committee on Professional Ethics of the American Statistical Association: https://www.amstat.org/ASA/Your-Career/Ethical-Guidelines-for-Statistical-Practice.aspx for more information.
The award shall honor an individual
The Award Committee shall identify a set of relevant journals from which to read papers.
The Award Committee is responsible for the of selection criteria and can recommend any modifications to COPSS.
Form and Presentation of Award
The award consists of a plaque, a citation, and a cash honorarium. It is presented at the COPSS Awards and Fisher Lecture session at the Joint Statistical Meetings (JSM). The amount of the award shall be such that the principal of the fund is left intact. Reimbursement for reasonable travel and hotel expenses to attend the JSM to receive the award provided to the if other funds are unavailable. The award will be presented by the Chair of the Award Committee or their designee. The recipient will be allowed time to acknowledge receipt of the award at the JSM.
