Final answer:
The overall percent agreement between observers is measured to assess the level of agreement or consistency between their observations or measurements. It is calculated by dividing the number of agreements between the observers by the total number of observations, and then multiplying by 100 to get the percentage.
Step-by-step explanation:
The overall percent agreement between observers is measured to assess the level of agreement or consistency between their observations or measurements.
It is calculated by dividing the number of agreements between the observers by the total number of observations, and then multiplying by 100 to get the percentage.
For example, if two observers recorded their measurements for a set of data and agreed on 80 out of 100 measurements, the overall percent agreement would be 80%.
