Texts: Introduction to the Practice of Statistics, 4th Edition, by David S. Moore
Course Description:
We are going to discuss basic concepts, methods, and applications of statistics in the natural sciences. We also will consider elementary probability theory, random variables, discrete and continuous probability distributions. Then we use them to study statistics and sampling distributions, estimation and hypothesis testing, linear regression. Credit is given for only one of MA 133M or one of the behavioral science statistics courses, but not both.

All exams except the final take place during class time. For these exams, all the questions are similar to the homework problems. Such questions may ask you to explain, for example, why a given formula makes sense. Students may bring a 3.5 x 5 inch note-card with them to the exam, and calculators are allowed.
It is expected that you will adhere to
the code of academic integrity and that all work on examinations will be your
own.
Grading Policy:
Your final grade in the course will be based on the following:
quizzes 10%, homework 25%, first midterm: 15%, second midterm: 15%, third midterm 15%, final exam: 20%.

Assignments:
We will have weekly homework. The homework problems associated with material discussed in class should be completed as soon as possible. Students should spend two hours out of class for every hour in class. This amounts to one hour per day (on average) for this course. Use this time to review class notes, work carefully through the text, and prepare solutions to the problems.
Mathematics is easiest to learn when studied in small, frequent chunks of time. The unconscious mind requires time to organize material presented by the conscious mind. Feed the unconscious mind regularly to keep it working! Try to do at least one hour of math every day.
I encourage you to work in groups but prepare your writing in your own words. Further, you will acknowledge group work and editing assistance as part of your documentation of the work. Please realize that in ALL writing and oral presentations at this college, and in all of academic life, respect for others' ideas is ALWAYS acknowledged by attribution and standard citations of sources. If you do not know what constitutes plagiarism, see Diana Hacker, Writer’s Reference, section R3, and the EC Book , or http://www.wsulibs.wsu.edu/plagiarism/main.html and then please talk with me about any details.
I will expect you to pledge all your assignments in accordance with the Eckerd College Honor Code: in its full form, we state,
On my honor, as an
No late homework will be accepted. Please hand in ones. However, you should be able to do all the homework problems including the red ones in the brackets.
