I have data from the lab where participants chose a probability from 0% to 100%.
The theoretical optimum is at 0%, obviously you cannot have a symmetric distribution around 0%.
I want to prove that participants in the lab differ from the theoretical optimum of 0%.
Wilcoxon signrank test (signrank variable=0) works fine in stata, but I wonder if the assumption of the symmetric distribution is violated so that I cannot use this test.
Anyone an idea of an alternative test for this problem?
