Darley and Latané (1968) asked subjects to participate in a discussion carried on over an intercom. Aside from the experimenter to whom they were speaking, subjects thought that there were 0, 1, or 4 other people (bystanders) also listening over intercoms. Halfway through the discussion, the experimenter feigned serious illness and asked for help. Darley and Latané noted how often the subject sought help for the experimenter as a function of the number of supposed bystanders. The data are presented below. What could Darley and Latané conclude from the results? What is the strength of any significant finding? Can you isolate the source of any significant association in this table?
