(requires Adobe PDF Reader)*

In the past four years, the GMAT has included standard deviation problems with increasing frequency. Integrated Learning's approach to statistical measurement, and, particularly to standard deviation, is comprehensive and focuses on complete mastery of the topic.

We believe standard deviation must be understood as a mathematical concept. We believe that because the test believes that. As a test taker, you will come across questions that require you to "get" standard deviation, not just derive it.

We present to you, in full, a lesson on Statistical Measurement and standard deviation. We hope it will give you an idea of how we work and the kind of approach we take on the GMAT.
