Design question and study plan

[RobinsonZ]

• [ ] Develop design question (currently: use an "open" button or a double-click action to open files from cards?)
• [ ] Study plan:
  • [ ] A description of tasks users will perform with your interface. Plan tasks that take no longer than 5 minutes. You will conduct your study during studio—keeping your tasks short means you can have lots of people participate in your study
  • [ ] The dependent variables (i.e., your measurements of the effects the change of the interface will have on users’ experience). The only requirement for this assignment is that you have at least one dependent variable that can be measured with a questionnaire item (like perceived task difficulty) and one that can be measured using more objective instruments (like task time, accuracy rate, or counts of interface events).
  • [ ] A brief description of how you will measure each of the dependent variables. This could include using a stopwatch, having the participant answer questionnaire items, and logging events from your interface code.
  • [ ] A testable hypothesis, describing how the independent variable relates to each of the dependent variables
  • [ ] A description of the kind of statistical test you can run for each hypothesis to validate whether there is a statistically significant effect of the interface variant on the dependent variable. You may wish to look at slides from class to recall the kinds of tests that can be used for different types of hypotheses.
