What is the target percentage for IOA agreement?

The target percentage for Interobserver Agreement (IOA) is set at 80%. This percentage indicates a strong level of consistency between observers measuring the same behavior or event. The rationale behind this target is to ensure that the data collected is reliable and valid. Achieving at least 80% agreement suggests that observers are likely perceiving and recording the behavior similarly, which is crucial for maintaining the integrity of the data and drawing accurate conclusions based on this information.

Higher percentages of IOA, such as 90%, may be ideal in certain contexts, as they reflect even stronger agreement. However, establishing the standard at 80% allows for a balance between practical observation conditions and the level of reliability needed for effective decision-making.

Options suggesting a lower percentage, such as 50% or 70%, do not provide a robust level of confidence in the observations, making them less appropriate as targets for IOA.
