When two raters interview the same sample of subjects and note the presence or absence of a number of characteristics, significance tests are provided for assessing whether agreement between the raters differs from subject to subject, or from characteristic to characteristic. When no such differences exist a simple index of agreement between raters is obtained by calculating the proportion of instances on which their decisions agree.
