Answer:
The percentage of inter-rater reliability is 80%.
Step-by-step explanation:
The rate of inter-rater reliability is the division of the number of intervals in which they agreed number of total intervals.
In this problem, we have that:
There are 10 intervals.
The observers agreed on 8 of them.
So the rate of agreement is 8/10 = 0.8.
As a percentage, we multiply the rate by 100, so 0.8*100 = 80%.
The percentage of inter-rater reliability is 80%.
