A software developer is testing the efficiency of two different user interface layouts (Layout α\alphaα, which is menu-driven, vs Layout β\betaβ, which is hotkey-driven) on the time taken (in seconds) by database administrators to complete a standard data migration task. To investigate this, the developer plans to use an experimental design where every administrator completes the task using both Layout α \alpha\,α and Layout β\betaβ.
Outline one weakness of using a repeated measures design in this study.
