Inter-rater reliability is one of the best ways to estimate reliability when your measure is an observation. However, it requires multiple raters or observers. As an alternative, you could look at the correlation of ratings of the same single observer repeated on two different occasions.

What are three methods of assessing reliability?

How do we assess reliability and validity?
  • We can assess reliability by four ways: ...
  • Parallel forms reliability. ...
  • Correlation between two forms is used as the reliability index.
  • Split-half reliability. ...
  • Internal consistency reliability. ...
  • This is called the Coefficient Alpha, also known as Cronbach Alpha. ...
  • Validity.


What are the tools of reliability?

These are:
  • Reliability Modelling.
  • Failure Modes and Effects Analysis (FMEA) and Failure Modes and Criticality Analysis (FMECA)
  • Reliability Centered Maintenance (RCM) and PM Optimisation (PMO)
  • Root Cause Analysis.


What are examples of reliability tests?

Reliability is a measure of the stability or consistency of test scores. You can also think of it as the ability for a test or research findings to be repeatable. For example, a medical thermometer is a reliable tool that would measure the correct temperature each time it is used.
