By having robert conduct all 15 of the first-round interviews, there is consistency of the rater during the interview process. This consistency is known as Reliability.
Give a brief account on reliability.
The term reliability describes how regularly or dependably a test assesses a trait. A test is said to accurately measure a characteristic if a person who takes it again receives results that are similar.
How can we take into account the case of a person who doesn't consistently receive the same test score? The following are a few potential causes:
- Transitory mental or physical condition of the test-taker. A person's psychological or physical state at the time of the test may have an impact on how well they do on it. The applicant's test results could be impacted, for instance, by varying levels of anxiety, exhaustion, or motivation.
- Environmental factors : The testing environment might differ from one test to the next, including in terms of room temperature, lighting, noise level, and even the test administrator.
- Test form : Numerous tests have multiple iterations or formats. Although the items on each form vary, they all aim to quantify the same thing. Parallel forms and alternate forms are terms used to describe several test configurations. Although they contain distinct items, these forms are made to have comparable measuring qualities. A test-taker might perform better on one form than another since the forms aren't precisely the same.
- Multiple raters : In some tests, the score is based on the rater's evaluation of the test-performance taker's or responses. The test taker's test results may vary depending on the raters' backgrounds, levels of experience, and frames of reference.
