 | How to conduct a Quantitative Usability Test Do you know how to measure usability? Do you have questions about the benefits and process for conducting a quantitative usability test? I've assembled answers to the 72 most common questions that arise from measuring usability. In this 64 page report I provide concrete examples and plenty of data from a dataset of 120 usability tests, the latest usability research and my decade of experience conducting quantitative usability tests. |
 | Usability Statistics Package Use these sets of calculators to compute the most common statistical tests on usability data. Compare small and large sample completion rates, compare task times, compare satisfaction scores, generate confidence intervals and compare a completion rate and task time to a criterion. This package takes the guess work out of what tests to perform on your usability data. |
 | Usability Statistics Package Expanded Calculate the common statistical tests, sample sizes and use some advanced statistical tests on usability data. This calculator package contains everything the Usability Statistics Package contains, but is expanded to included sample sizes calculators for margins of error and power calculations for comparing two applications. It also contains ANOVA and Chi-Square tests to compare multiple means or completion rates. This package takes the guess work out of what tests to perform on your usability data. |
 | Confidence Interval Comparison Calculator Compare the four different binomial confidence calculations: Adjusted-Wald, Wald, Exact and Score in an Excel spreadsheet. This calculator contains all the formulas for you to easily compare the methods and integrate them into your Excel workbooks. |
