A Study Of Fidelity Level And Task/Non-Task Based Testing Scenarios On The Effectiveness Of Usability Testing, Joshua R. Dolecal
A Study Of Fidelity Level And Task/Non-Task Based Testing Scenarios On The Effectiveness Of Usability Testing, Joshua R. Dolecal
Master's Theses - Daytona Beach
Advances in usability are directing developers towards creating a better and all around friendlier environment for users. Unlike when buying a physical product where you purchase it first and then experience its usability, web site usability is immediately present. So, if a site doesn't meet our needs, we as users, are quick to look elsewhere. Some research has suggested that fidelity makes no significant impact on users' ability to locate errors or problems in a web site. This paper is intends to investigate the interaction between fidelity and task vs. non-task user testing with regards to the types of problems …
An Analysis Of The Effects That Several Design Variables Have On The Accuracy And Precision Of Glass’ Delta And Hedges’ G, Joshua N. Dryer
An Analysis Of The Effects That Several Design Variables Have On The Accuracy And Precision Of Glass’ Delta And Hedges’ G, Joshua N. Dryer
Master's Theses - Daytona Beach
Effect size is the standardized effect that some treatment has on a sample of a population. In particular, Hedges' g and Glass delta are mean difference effect size estimators that are used to compute the effect sizes found in an experimental situation. A confidence interval is an interval placed around a point estimate that indicates the precision with which the point estimate can be made. This paper provides an explanation of the concept of effect size estimation and confidence interval calculation, the different methods that can be used to calculate effect sizes and confidence intervals, and applies these methods in …
