One definition of management is the "judicious use of means to accomplish an end." In this information age, the judicious use of information is among the most important skills available to managers without regard to what they manage. Though in prior times the cost of acquiring information was significant, we are entering (or perhaps are in) an age in which the separation of relevant and irrelevant information is among the hardest and most important tasks facing managers. Statistics, as summaries of large amounts of information, provide a crucial tool for informing quality managerial decisions.

Robert W. Walker, Ph. D. is Associate Professor of Quantitative Methods in the Atkinson Graduate School of Management at Willamette University. Though his Ph.D. is in political science, Professor Walker has taught statistics and research methods to both undergraduate and graduate students at Dartmouth College, Texas A&M University, Washington University in Saint Louis, and Rice University prior to his arrival at Atkinson in addition to courses in political economy. He was a regular instructor in the National Science Foundation's Empirical Implications of Theoretical Models summer program at Washington University in Saint Louis and has regularly taught courses in the analysis of longitudinal data at the Essex Summer School in Social Science Data Analysis in the United Kingdom.

His joint work received the Warren Miller Prize for the best published paper in 2009 in Political Analysis, the journal of the Society for Political Methodology and the most cited journal in Political Science during the most recent evaluation period. His published work spans international political economy, political methodology, and the political economy of state and municipal bond markets.

Statistics - a branch of mathematics dealing with the collection, analysis, interpretation and presentation of masses of numerical data - is a crucial tool for modern managers. If used correctly, statistics are efficient methods for uncovering patterns and informing decision making. At the same time, if used incorrectly, statistics can lead us wildly astray.

At Atkinson, the tools of statistics are an important part of an overall training program not as an end, in and of themselves, but as a means to assist managers in making informed decisions that enhance their organizations and facilitate the outcomes that the managers seek to achieve. Statistics are certainly not a silver bullet as they can both inform and deceive. The objective of statistics education at Atkinson is to provide future managers with the foundations to separate useful and harmful statistical information and to appreciate the fine details that distinguish the useful from the harmful across a broad variety of management contexts.
