What this indicates is that the probability of response (or non-response) is not correlated with (i.e., appears to be independent of) the vote-count per respondent. (I checked it per respondent type, and it is comparably close across types: large = 7/21 = 33.333%, small = 22/64 = 34.375%, individual = 55/166 = 33.133%) Why this should be remarkable or not is an open question. :-) Why would you hypothesize that they would be different? Did you think institutional members would be systematically different (on average) from individual members, in this regard? Do you have a theory of response that predicts this?
