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

Statistical Data Analysis

For clients who need help running statistical analyses on:
  • usability data
  • sales data
  • web-logs (conversion rates typically)
  • experimental data
  • surveys
..to answer specific questions such as :
  • What are the key drivers of customer loyalty?
  • What is the probability a user will purchase a product?
  • Which promotion has a statistically higher conversion rate?
  • Which experimental condition yielded the highest ratings?
  • What sample size do we need?
I conduct analysis on both small and large datasets (10 rows to 1 million rows) and am proficient in the major statistical packages Minitab, SPSS and SAS, although I typically program my own statistical functions and calculators.
