The partial-IOA interval agreement. To avoid the described disadvantage associated with the use of the IOA algorithm for the total number, the observation period is divided into small intervals, the partial approach of interval concordance (sometimes called “mean neck-per-interval” or “block-by-block”) dividing the observation time into small intervals, and then examining the intervals within each interval. This increases the accuracy of the chord ite by reducing the likelihood that total numbers have been deducted from the different events of the target responses within the observation. By deriding the example of Figure 1 into small steps of time/intervals (15 intervals of 1 m), the partial agreement approach calculates the IOA at intervals and divided by the total number of intervals. In this case, the IOA would be 50% (or 0.5) for the interval e. 4, 100% (or 1.0) for intervals 5 to 14 (both agreed that 0 target responses appeared), but 0% for intervals 1 to 3 and interval 15. Therefore, the partial agreement approach would be derived at regular intervals, adding the IOA values (in this case 10.5) by the total number of intervals (15), i.e. a more accurate and lower IOA percentage (70%) Gives. 100% value determined by the total counting algorithm. Precise agreement IOA. It is clear that the approach to partial agreement at regular intervals is stricter than the overall census as a measure of the agreement between two observers. However, the most conservative approach to the IOA would be to overlook any discordance as a total disagreement during these intervals and to regard any disparity as null and void.

A specific agreement is such an approach. Using this ratio, only specific agreements over an interval lead to this interval being estimated at 100% (or 1.0). The example of our race example would allow access to specific agreements for intervals of 5 to 14 or 10 of the 15 intervals. The division of 10 by the total number of intervals (15) gives an IOA of 66.7% – a slightly lower approval rate than the approach of the partial agreement at regular intervals. In the block-by-block method, the smallest of the sums of the two observers is divided within 10s by the larger one. This gives a score between 0 and 1 for each interval. For the calculation of the agreement, if the two observers did not obtain attendance during an interval, these intervals are estimated at 1. Values are added up at all intervals and divided by the number of intervals, and the result is converted into a percentage to provide a percentage agreement index. This description of the calculation of the block-by-block agreement applies to all research articles in our analysis that have been identified as identified by the method, and it has been confirmed by users of the algorithm.
