Inter-observer reliability is demonstrated when two observers...

• A. Encode data in different ways.
• B. Observe independently but reach inconsistent results.
• C. Observe the same behaviours independently and produce similar results.
• D. Ask participants to confirm their behaviours.

Answer: (C)

Inter-observer reliability is about consistency across different observers recording the same events. It is demonstrated when two observers watch the same behaviours independently and arrive at similar results, showing that the coding system yields stable measurements regardless of who does the observing. This helps ensure the data reflect actual behaviour rather than individual observer bias. If they encoded data differently, or if they observed independently but produced inconsistent results, reliability would be compromised. Asking participants to confirm their own behaviours bypasses observer judgments and wouldn’t measure agreement between observers.
