### Math 225 Course Notes

### Course Introduction

**Your Professor:**
Professor Bret Larget began teaching at Duquesne University in the fall
of 1994.
He attended the University of Minnesota as an undergraduate where he studied
mathematics,
graduating in 1989.
He attended graduate school at the University of California at Berkeley
where he earned a Master's (1991) and a Ph.D. (1994) in statistics.
Professor Larget is married and has two young children.
Stop by his office to see pictures and fine examples of pre-school artwork.

Professor Larget is a native of Wisconsin and reminds you that
the Green Bay Packers won THEIR most recent Super Bowl.

**Syllabus:**
Check your syllabus for important dates,
and for a tentative outline of the course.

**Office Hours:**
Office hours are on Wednesdays from 1:00 to 3:00,
on Thursdays from 4:00 to 5:00, or by appointment.

**Homework:**
Frequent assignments will be made throughout the semester.

You are not expected to have a math background beyond highschool algebra.
Most of what you will be expected to learn this semester is conceptual,
and does not involve extensive calculation or algebraic manipulation.
You will learn how to use statistical software to carryout tedious statistical
computation.
You should obtain a calculator with statistical capabilities.
If you are getting a new calculator,
I advise purchasing a two-variable statistics calculator,
which sells for as low as $20.

At the end of the course, you should be able to:

- create and interpret graphical summaries of data,
- calculate and interpret numerical summaries of data,
- understand the chance variation of statistics calculated
from random samples,
- understand the statistical reasoning behind the various methods
of statistical inference,
- interpret the output of statistical software,
- and understand the statistical methods that you will encounter in
your future research methods courses
and in articles written in your field.
