Table 2.
Analysis of deviance table (Type II Wald chi-square tests) for linear models on time to solve by successful attempt number
| Puzzle type | LRΧ2 | df | P |
|---|---|---|---|
| Flap lid (log) | 1.58 | 1 | 0.209 |
| Slide lid (sqrt) | 0.62 | 1 | 0.430 |
The first two successful attempts are considered for flap (n = 8) and slide lid puzzles only (n = 10).
