Final answer:
The HR manager used test-retest reliability, a method that estimates the reliability of a measurement procedure by checking if it produces consistent results across multiple occasions under the same circumstances.
Step-by-step explanation:
An HR manager used the identical measurement procedure to assess the same characteristic over the same group of people on different occasions. The method of estimating reliability that was used is referred to as test-retest reliability. This method is predicated on the consistency of the measurement across multiple test instances. If the results from the different occasions are similar or consistent, the measurement is deemed to have high test-retest reliability. It is crucial for ensuring that the measure is stable over time and is particularly relevant in fields such as human resources and psychology.
Test-retest reliability is essential for various data collection instruments across many fields to demonstrate the ability to produce consistent and reproducible results. For instance, when job analysis reliability is in question, using test-retest reliability can help an HR manager determine the dependability of the job analysis process by making sure the method yields similar results when administered again under the same conditions. The reliability of the measurement is a fundamental aspect to consider, especially when the results may influence significant decisions regarding employment and organizational practices.
