Reliability and replicability

Reliability and replicability.

• Candidates should be able to:.
• describe different types of reliability, including inter-rater and inter-observer reliability, test-retest reliability.
• evaluate studies based on their reliability.
• apply knowledge of reliability to a given novel research situation.

This matters because reliability and replicability determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply reliability and replicability to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Reliability and replicability is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
