Can you use statistics with usability data? In this tutorial Jeff will explain how usability metrics can be statistically analyzed. He’ll start with addressing the common concerns with using statistics: sample sizes are too small and data aren’t normally distributed. Then he will walk through examples using confidence intervals and how to detect if there is a statistical difference between two products.
