Document Summary

1. inter-observer agreement (ioa): used to determine whether target behavior is being measured consistently across observers; exact agreement (no pc); proportional/partial agreement (pc); scored by interval-by-interval agreement. 2. ioa calculations for frequency recording: ioa is expressed as percentage (small freq/large freq); duration recording- small duration/large duration. 3. interval recording ioa calculations: check the agreement between the two observers in each interval; then divide the number of intervals with agreement by the total number of intervals. 4. occurrence only ioa: intervals where both observers scored the behavior are counted as agreements, intervals where both observers did not score an occurrence of the behavior are not used in the calculation. 5. non-occurrence only ioa: intervals where both observers agreed the behavior did not occur are counted as agreements ; intervals where both observers scored an occurrence of behavior are not used in the calculation.
