The formula for computing IOR on data collected from interval recording is:
A)disagreements divided by the total number of intervals, multiplied by 100%
B)disagreements divided by agreements + disagreements on the occurrence of a behavior, multiplied by 100%
C)agreements divided by agreements + disagreements on the occurrence of a behavior, multiplied by 100%
D)agreements divided by disagreements on the occurrence of a behavior, multiplied by 100%

Interval recording measures the presence or absence of a behavior within a specific time frame or interval. To compute the IOR, we need to know the number of agreements (when the behavior occurred) and disagreements (when the behavior did not occur) in each interval. The formula for IOR is agreements divided by agreements plus disagreements, multiplied by 100%. Therefore, the correct answer is C, which is agreements divided by agreements plus disagreements on the occurrence of a behavior, multiplied by 100%.
