Document Summary

Is the situation we"re studying, the same thing we are interested in: what happens in the real world, participant observation: an observational data collection technique in which the observer participates with those being observed. Methods are adjusted as a result of pilot testing: observe public play areas at a mall. Inter-observer reliabilities were computed on the number of times each of the five discipline tactics occurred during the tantrums witnessed. Each test revealed substantial to almost perfect agreement. Cohen"s kappa ( ) for each of the five disciplines ranged from . 79 to . 97. Example 1: 2 raters (r1; r2) categorize 10 parental behaviours as a threat (yes vs no). In 5 cases they agree behaviour is a threat. In 4 cases they agree behaviour is not a threat. Note that % agreement = 9 / 10 = 90% R2 kappa ( ) = [9 - 5] / (10 5) = 4 / 5 = . 8.
