100. Introduction to Statistical Reasoning.
No credit granted
to those who have completed or are enrolled in Soc. 210, Stat.
402, 311, 405, or 412, or Econ. 404. (4). (MSA). (BS). (QR/1).
This course is designed
to provide an overview of the field of statistics. Course topics
include methods of analyzing and summarizing data, statistical
reasoning as a means of learning from observations (experimental
or sample), and techniques for dealing with uncertainties in drawing
conclusions from collected data. Basic fallacies in common statistical
analyses and reasoning are discussed, and proper methods indicated.
Alternative approaches to statistical inference are also discussed.
The course emphasis is on presenting basic underlying concepts
rather than on covering a wide variety of different methodologies.
Course evaluation is based on a combination of a Thursday evening
midterm examination, a final examination, and teaching fellow
input. The course format includes three lectures and a laboratory
(1 hour per week). Cost:2

170. The Art of Scientific Investigation.
(4). (MSA).
(BS). (QR/1).
The objective of this
course is to introduce students to the learning process in a non-deterministic
environment. An appreciation for measurement, bias, and variation
is essential to formulate questions and learn about things. Underlying this course is the Edwards Deming philosophy. Deming, an American
statistician, was invited to Japan in the early 1950's to help
improve the quality of mass produced items. His success in Japan
is, in part, responsible for our current balance of trade deficit;
and here the Ford Motor Co. has also attained a larger market
share as a result of his ideas. Implementation of the Deming message
requires a critical appreciation of variation and the scientific
method. Specifically, we will discuss: (1) Historical attempts
to learn and the advent of the modern scientific method. (2) The
differences between special or assignable causes and common causes
of variation. Before we can learn how a process operates, the
process must be stable. (3) Differences between observational
and controlled randomized studies and associated ethical issues.
(4) The 'what' and 'how' of measurement and the quantification
of uncertainty-subjective and frequency notions of probability.
(5) Understanding bias and variation. (6) How to use bias to design
efficient studies. (7) Differences between enumerative and analytic
studies. Many of the ideas will be introduced through experimentation (e.g., the red bead and funnel experiments), and the
mathematical level will not require more than a modest background
in high school algebra. The course format includes three lectures
and a laboratory (1.5 hours per week). Cost:2

In this course students
are introduced to the concepts and applications of statistical
methods and data analysis. Statistics 402 has no prerequisite
and has been elected by students whose mathematics background
includes only high school algebra. Examples of applications are
drawn from virtually all academic areas and some attention is
given to statistical process control methods. The course format
includes three lectures and a laboratory (l.5 hours per week).
The laboratory section deals with the computational aspects of the course and provides a forum for review of lecture material.
For this purpose, students are introduced to the use of a micro-computer
package and the Macintosh computer. Course evaluation is based
on a combination of three examinations GIVEN WEDNESDAY EVENINGS, a final examination, and teaching fellow input. Cost:2

Processes. Math.

This is a course on the theory and applications of stochastic processes, mostly on
discrete state spaces. It is a second course in probability which
should be of interest to students of mathematics and statistics
as well as students from other disciplines in which stochastic
processes have found significant applications. The material is
divided between discrete and continuous time processes. In both, a general theory is developed, and detailed study is made of some
special classes of processes and their applications. Some specific
topics include generating functions; recurrent events and the
renewal theorem; random walks; Markov chains; branching processes;
limit theorems; Markov chains in continuous time with emphasis
on birth and death processes and queuing theory; an introduction
to Brownian motion; stationary processes and martingales. This
course is similar to EECS 502 and IOE 515, although the latter
course tends to be somewhat more oriented to applications. The
next courses in probability are Math 625 and 626, which presuppose
substantial additional background (Math 597). WL:2 (Woodroofe)
