User Story
As a psychologist, I want to see error bars on learning curves so I can do an "eyeball test" to see if two points are reliably different (if there error bars aren't overlapping), which will give me more confidence that the conditions are different.
Notes/Comments
- Adapted from Bob Hausmann's DataShop demo. See Error Bars on Wikipedia.
- Error Bars [Bob Hausmann, Winter Workshop 1/23/2008]
- Bob mentioned the need for Error Bars in his presentation at the DataShop Work Shop held in January 2008.
- Bob introduced something he's seen from another researcher: error bars used to indicate statistical significance--overlapping bars between points means no statistically significant different, but no overlap means there is statistical significant difference. This is a visual t-test.
