What Do All of These Means Mean?

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

There is a strong desire to reduce the performance of a computer system to a single number. Typically this is done using one of several different statistical means, such as the arithmetic, harmonic, or geometric means. In this course you will learn how to calculate the different types of means and how to quantify the variability in a group of measured values. More importantly, you will learn when each of the different types of mean values should be used.

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.
