Reliablity

• Reliability refers to how consistent or depenable a test is. A reliable test carried out in the same circumstances on the same participants should always give the same results.
• Internal Reliability - Different parts of the test should give consistent results when separated.
• External Reliability- the test should produce consistant results regardless of where it is used.
• Inter-observer Reliablity: The test should give consistent results regardless of who administers it.
