Darley and Latané (1968) recorded the speed with which participants summoned help for a person in trouble. Some participants thought that they were alone with the person (Group 1, n 5 13), some thought that one other person was there (Group 2, n 5 26), and others thought that four other people were there (Group 3, n 5 13). The dependent variable was speed (1/time 3 100) to call someone for help. The mean speed scores for the three groups were 0.87, 0.72, and 0.51, respectively. The MSerror was 0.053.
