The data collection procedure for PD's target behaviors will involve direct observation and recording of each instance of the behavior using a frequency count method. The observer will use a stopwatch to record the duration of each behavior. Each instance of the target behaviors will be recorded in a data sheet, which will include the date, time, duration, and context of the behavior. The data will be collected during PD's school hours, including lunch and recess times.

question :

description of an interobserver agreement (IOA) procedure that could be used to measure the accuracy of the data collection. Include the name of the IOA procedure and the equation used to measure it. Also, include a rationale for why you selected that IOA procedure.
