Statistically Comparing Two Alternatives

David J. Lilja, Ph.D., P.E.

Due to measurement noise, it often can be difficult to determine whether a change made to a system had any real impact. Measurement noise also makes it difficult to compare the performance of two different systems. In this course, you will extend your understanding of confidence intervals to determine if there is a statistically significant difference in the performance of two alternatives. You will learn about both before-and-after comparisons and comparisons using unpaired measurements.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

This course is based on the author's book, Measuring Computer Performance: A Practitioner's Guide. The listed price for this course has been reduced to compensate for the cost of purchasing the required chapter in PDF format online through ebooks.com.
