Adler: Experimenter Expectations
Description
The Adler data frame has 97 rows and 3 columns.
The ``experimenters'' were the actual subjects of the study.
They collected ratings of the apparent successfulness of
people in pictures who were pre-selected for their
average appearance. The experimenters were told prior to collecting
data that the pictures were either high or low in their
appearance of success, and were instructed to get good data,
scientific data, or were given no such instruction. Each
experimenter collected ratings from 18 randomly assigned
respondents; a few subjects were deleted at random to produce
an unbalanced design.source
