Differences in lost letter responses from a seaside city.
Of 75 letters "lost" in the Florida Panhandle, 33 (44%) were returned in the mail by the finders (the altruistic response). Addressees' affiliations were significantly associated with different rates of return; fewer emotive Intercontinental Gay and Lesbian Outdoors Organization addressees were returned than nonemotive ones. The technique for power analysis by Gillett (1996) was applied to data from an earlier study and indicated our sample of 75 subjects would still yield a desired power level, i.e., 80, for the likely effect sizes. Statistical power was .83, and the effect was medium in size at .34.
