Dependent variables can also be measured in more than one way, and the amount of information provided will depend on how the variable is measured. The two experiment that tested the effects of “anxiety” on affiliation used the same dependent variable (desire to affiliate), but the way affiliation was measured differed somewhat. In the Schachter (1959) experiment, subjects simply stated whether they wanted to wait with others, alone, or had no preference. But Sernoff and Zimbardo (1961) had subjects rate the intensity of their preference on a scale from 0 (very weak preference) to 100 (very strong preference). The second type of measurement provides the researcher with additional information and uses a different level of measurement.
