This dataset accompanies the paper "Group size effects and critical mass in public goods games", https://doi.org/10.1038/s41598-019-41988-3

It records participant decisions in a set of binary one-shot Public Goods Games with curvilinear payoff function (see details in the paper).

The explanation of the data fields is present also in the metadata of the file:
# Cooperation: 0=defection, 1=cooperation, 99=the participant did not make the decision

# Group: interacting group size (N)

# Treatment: Critical Mass Nc

# dropout: 1=the participant did not make the decision, 0=the participant made the decision

# incompleted: 1=participant did not make all the decisions of the experiment; 0=participant did made all the decisions of the experiment

# female: 1=female, 0=male
