4 event recording IOAs - total count mean count per interval exact count per interval trial by trial 2 Timing/Duration IOAs - total duration IOA mean duration or IRT per occurrence IOA Total Count IOA - simplest method for event recording, overestimates the extent of actual agreement smaller # x 100% ______________________ larger # Mean Count Per Interval IOA - observers record the number of occurrences of the behavior within each interval Int1 + Int 2+ Int 3+Int 4+ _________________________________ Total # of IntExact Count Per Interval IOA - The percentage of intervals in which 2 observers record the same count, the most strict event recording IOA method # of intervals of 100% aggrement _______________________________________________ x 100% total # of intervals Trial by Trial IOA - The agreement between to observers who measure the occurrence or nonoccurrence of behavior during DTT # of trials agreement ______________________________ x 100% total # of trials Total Duration IOA - add up all of observer 1s data and all of observer 2s data then do divide then shorter duration _______________________ x 100% longer duration Mean Duration or IRT Per occurrence IOA - used to calculate duration per occurrence data duration IOA B 1+ duration IOA B 2+ duration B 3 _____________________________________________________________________ the number of Bs with duration IOA Interval By Interval IOA, Point by Point Agreement Ratio - the primary observer's data for each interval is matched to the secondary observer's data for the same interval# of int. both recorders are in agreement __________________________________________________________ x 100% total # of intervals Scored Interval IOA - only uses intervals in which both observers scored an occurrence of the behavior # of ints. both recorders record occurrence x 100% _____________________________________________________________ # of ints. at least 1 recorder record occurrence Un-scored Interval IOA - minimizes the effects of chance agreement for interval data on behaviors that occur at a very high rate or a very low rate # ints. both recorders record non-occurrence _______________________________________________________________ 3 of intervals at least 1 recorder recorder non-occurrence x 100%
