N = number of inactive individuals whose behavior was analyzed from videotapes

Total = number of bumps received/given by all inactives sampled; mean = total bumps/N

SD = standard deviation of mean; minimum = minimum number of bumps received/given by an inactive in the sample

Maximum = maximum number of bumps received/given by an inactive in the sample

Bumping propagation rate = total bumps given divided by total bumps received
