The attached document observational data represents the results of two observers concurrently observing the behavior of a student (the behavior is 'engaged in assigned work') using a momentary time sampling method (15 seconds). Since they used the same cuing device this document can be used to compute interobserver agreement. Compute the scored interval IOA (occurrence IOA), considering observer 1 as the prime observer. The IOA in your answer should be rounded to the nearest two digit number with decimal point (e.g. .54). Please make sure you follow that format and do not include any additional digits or signs.
