Course overview

Today's federal employees require a basic understanding of statistics in order to properly analyze information, recognize important trends, and recommend or evaluate appropriate actions. The course begins with a refresher on essential arithmetic operations and algebraic notations used in basic statistical calculations and formulas. The course then covers both descriptive and inferential statistics for quantitative and categorical data. The emphasis throughout the course is on understanding the concepts underlying the statistical formulas and understanding which formula to use in a given analytic situation. Each formula is presented with examples and then practice is provided in calculating and interpreting the formula. The course manual serves as a reference for all statistical concepts and formulas for use on the job.

Who should attend?

Government employees and contractors who need to understand or perform basic statistical calculations and interpretations at work, including individuals who need a refresher course and those who have never taken a course in statistics.
