Document Summary
Graph data to make data decision rules. Can be measured in a at least one dimension. How many times a behavior was observed during a specific period of time. Documents whether the behavior occurred during a particular period. Divide the total number of intervals where the behavior occurred by the total number of intervals and multiply by 100 to determine the percentage of intervals during which the behavior occurred. To calculate inter-observer agreement, go interval by interval and divide the number of agreements by the total number of intervals and multiply by 100. Continuous behaviors (e. g. , crying, screaming) however underestimates the overall duration of the behavior because if a behavior occurs, but not for the entire interval, it is not recorded or documented as occurring. Reactivity break complex tasks down in a sequence of smaller steps identify the time of day the problem behavior most often occurs individuals alter their performance when they are aware they are being observed.
