STAT 103: Fundamentals of Statistics

Course Details
Credit Hours: 3

None. Fulfills CORE Quantitative Analysis requirement.

Description:  An introduction to statistical reasoning. Students learn how statistics has helped to solve major problems in economics, education, genetics, medicine, physics, political science, and psychology. Topics include: design of experiments, descriptive statistics, mean and standard deviation, the normal distribution, the binomial distribution, correlation and regression, sampling, estimation, and testing of hypothesis.

C.H. Brase and C.P. Brase. Understanding Basic Statistics, 7th ed (WebAssign eBook). Cengage.

Instructions for students to obtain the e-book and to use WebAssign:Once your instructor has uploaded the class roster to WebAssign, your personal class page will be activated. You will access it with your Loyola ID and password as detailed below. 


1.    Go to www.webassign.net/luc/login.html(Note the change in URL from previous semesters.)

2.    Use the LOG IN @ LOYOLA UNIVERSITY CHICAGObutton in the center of the page. The LOG IN button in the upper right-hand corner should NOTbe used.

3.    Selecting the Loyola login button will bring you to a standard Loyola login page, where you will enter your Loyola ID and password.

4.    Successful login should bring you to a WebAssign home screen from which you can access any of your courses having a WebAssign component.

5.    Select the desired course. If you have not already registered an access code for the course, a notice will be displayed with three choices:

o    Enter an access code (purchased at the Loyola Bookstore or from the Acadiem website),

o    Purchase an access code (online from WebAssign), or

o    Continue the free trial.

Select the appropriate choice to access the e-book and homework assignments.

6.    If you purchased an access code for the Larson text in a previous semester, you do not need to purchase another code.

7.    If at any time you run into technical difficulty using WebAssign, you can contact WebAssign directly by email or phone. Visit https://webassign.com/support/student-support/to get started.
