Many science and engineering college degree programs require lower-level courses in statistics before students can move on to more in-depth program study. If you have not taken an official course in statistics but already know most of the material, you may want to take the DSST Principles of Statistics exam to receive college credit. Once you receive credit for statistics, you will be free to move on to the courses you really need to take.

DSST exams can be a good way to earn credit for a course without taking the time and extra money to complete that course in a traditional classroom setting. Before registering for the DSST Principles of Statistics exam you should check with your own college to make sure the DSST exam is an acceptable substitute for classroom time.

**The DSST Principles of Statistics exam covers five main areas:**

- Foundations of Statistics – 20%
- Probability – 15%
- Correlation and Regression – 20%
- Sampling Distributions – 20%
- Inferential Statistics – 25%.

You will be allowed to use a nonprogrammable calculator on the exam, and scratch paper is provided.

When you are studying for the exam, you should review a DSST Principles of Statistics study guide, which provides a detailed outline of what will appear on the exam. You may also want to check out some introductory statistics textbooks.

Most testing centers offer the Internet-based DSST Principles of Statistics exam, and your scores will be available immediately after completing the exam. If you would like your scores sent to a school of your choosing, you will need to enter the school code on the registration form.
