Activity 1 - Reliability vs. Validity

It refers to the accuracy or truthfulness of a measurement instrument or procedure, meaning how well it measures what it is intended to measure.

• Reliability
• Validity
• Precision
• Consistency

It indicates the extent to which the results of a study or measurement can be replicated under the same conditions.

• Accuracy

• Stability

• Reliability

• Validity

The consistency of a measure when the same test is administered to the same participants at different points in time.

• Content validity
• Parallel forms reliability
• Internal consistency
• Test-retest reliability

How well a test correlates with an established measure taken at the same time.

• Concurrent validity
• Face validity
• Construct validity
• Predictive validity

The extent to which all items in a test measure the same concept or construct, often assessed using Cronbach’s alpha.

• Item difficulty
• Construct validity
• Test-retest reliability

• Internal consistency
