Course Description

 Kenji Hakuta, Professor e-mail hakuta@stanford.edu Office Hours: by appointment (send e-mail), Cubberley 228 I will generally be in the Big Tree classroom a half-hour before each lecture, and will hang around after class to answer questions. Carrie Oelberger , Teaching Assistant e-mail: carrie.oelberger@gmail.com

The primary objective of the course is to introduce you to the major basic concepts in descriptive and inferential statistics, and to prepare you for subsequent statistical courses in multivariate statistics and beyond. (If you do not intend on taking subsequent statistics courses, you should register for Education 150.) This course begins with methods to describe and summarize frequency distributions. This is followed by various methods to describe the relationships between two variables. Finally, we provide an introduction to probability theory methods to draw inferences about the relationship between samples used in studies to the universe from which the samples were drawn. You will also be introduced to a statistical software program, SPSS. The course is meant to be informative and fun (yes, fun!), and we guarantee everyone that after this course, you will want to know more, and that the world of statistical thinking will never seem the same.

Exams. There will be two take-home exams during the course, with problems similar to those found in the homework problems. These exams are under the honor code. Students may not discuss the problems with others until the problems have been turned in.

Grading. Since this is a prerequisite course for the statistics sequence, the intent is to enable all students who put in the effort to pass. The course will be graded pass/no pass. Homework assisngment and exams will be graded in such a way as to give feedback on your command of the materials. Instructors are committed to alerting students who are in trouble, and to suggest corrective steps.
