Measuring Usability
Quantitative Usability, Statistics & Six Sigma by Jeff Sauro

About Measuring Usability

Measuring Usability LLC is a quantitative research firm based in Denver, Colorado USA focusing on the statistical analysis of human behavior and quantifying the user experience. Since 2004 we've been helping clients answer questions such as:

  • How usable is an application?
  • What is the probability a user will purchase a product?
  • How large of a sample size do we need?
  • Which design is preferred?
  • Which design has a statistically higher conversion rate?
  • How long will it take users to complete tasks?
Measuring Usability LLC provides more than intuition and qualitative insights about products and designs. We provide meaning through measurement.
