Ran Cory's bar-chart versus pie-chart experiment (available at http://piechartssuck.com/) with 3 participants, and got:
- Bar-chart mean error: 2.133
- Pie-chart mean error: 1.733
- P-value: 0.50
Slightly surprising to swing the way of pie-chart estimating being more accurate, but the p-value indicates that the effect is small enough that we need more participants to reliably detect it.
