  1. Dependent variable in all models: Number of pumps on each balloon that did not burst. Model 1 and Model 2 were fit to the balloons of the initial phase, Model 3 and Model 4 were fit to the balloons of the subsequent phase. For a more detailed description of each model, see main text. With the treatment contrast, the reference level of a given factor was used to estimate the other levels. These were baseline condition and Bin 1. Significant effects are in bold. SE: standard error; SD: standard deviation.
