Please note: This course will be taught in hybrid mode. Hybrid delivery of courses will include synchronous live sessions during which on campus and online students will be taught simultaneously.
Robert W. Walker is Associate Professor of Quantitative Methods in the Atkinson Graduate School of Management at Willamette University where he teaches statistics and data science. He earned a Ph. D. in political science from the University of Rochester in 2005 and has previously held teaching positions at Dartmouth College, Rice University, Texas A&M University, and Washington University in Saint Louis. He researches models as treatments for observational data and distributed lag variants of the between-within model, and semi-Markov processes for time-series, cross-section data. He previously taught four iterations in the U. S. National Science Foundation funded Empirical Implications of Theoretical Models sequence at Washington University in Saint Louis and has been an honorary instructor in panel data and time-series/panel data [joint with Harold D. Clarke from 2019 to 2021] at the Essex Summer School since 2010. His work with Curt Signorino and Muhammet Bas was awarded the Miller Prize for the best article in Political Analysis in 2009.
This course provides an introduction to applied statistics with a focus on management applications. The course begins with numerical and graphical summary methods for data, e.g. means, standard deviations, and percentiles, before introducing probability and probability distributions. We next turn to inference in the form of confidence intervals and hypothesis tests where we encounter the key probability distributions (normal, t, chi-square, F) deployed in core statistical methods that we examine: crosstabulation, t-tests, analysis of variance, correlation, and bivariate and multivariate regression. For computation, we will rely on R and, in particular, a graphical user interface for R [radiant] that contains many of the most useful tools for report and presentation construction using RMarkdown tools.
Participants will become familiar with a wide range of statistical methods for analysing observational data that are common to both academics and professionals in management and in the social and behavioral sciences. Participants will also gain some familiarity with R’s basic structure and more intimate familiarity with useful tools for report construction combining numerical outputs and graphical techniques built on RMarkdown through the graphical user interface for R known as radiant.
This is an introductory course and participants are not required or assumed to have anything more than basic mathematics. Supplemental materials will provide students with additional tools for embarking on a more thorough journey of the R language for statistical computing and the use of markdown for document construction.
Representative Background Reading/Preparation:
A working R installation will assist in hitting the ground running. Details and a tutorial for installation will be made available in advance of the first meeting along with information about the supplemental materials that will assist students in making the most of the materials in advance of a compressed course.
