I think inter reliaiblity is when you are consistent as a researcher in coding something, so you're the only one coding it, so you should have good inter rater reliability. If you have multiple coders of something, and you have high agreement among coders, then you have good inter-rater reliability.
Inter-reliability refers to the consistency and agreement between multiple raters or observers when assessing the same phenomenon. It is used to determine the degree to which different individuals or systems produce similar results when measuring the same thing, helping to ensure the validity and reliability of data collected or interpretations made.
