We recalculated the cooperation rate in each sub-case according to the number of cooperators in the preceding trial (0 to 4); this excludes the decisions of the corresponding participant.
One can thus identify an optimal initial cooperation rate to facilitate the system to reach equilibrium state quickly.
Mr. Poltrack of CBS said that in a random sample, which the sweep survey is, anything under a 50percentt cooperation rate could be called "statistically invalid".
If participants were increasing cooperation towards high contributors, we would expect cooperation rates towards high contributors in the treatment to be higher than the baseline cooperation rate observed in the control.
Of these participants, 2695 completed the survey (cooperation rate, 36.3%; Fig. 1).
Overall, 2695 subjects completed the survey (cooperation rate 36.3 %; Fig. 1).
Of them, 2,695 subjects completed the survey (cooperation rate: 36.3%, Fig. 1).
Eventually, 1507 subjects completed the survey, since 191 individuals suspended the interview (cooperation rate: 37.2%).
After 352 individuals suspended the interview, 2,695 subjects completed the survey (cooperation rate, 36.2 %; Fig. 1).
Of these 3,114 participants, 352 individuals suspended the interview, leaving 2,762 subjects who completed the survey (cooperation rate of 37.2%; Figure 1).
The overall response rate for the NYCHA study was 34.7 %, with a cooperation rate of 93.4 % for individuals reached by phone.
