2. Inter-Rater or Inter-Observer Reliability
3. Parallel-Forms Reliability
4. Internal Consistency Reliability
The type of reliability to be used would, in part, depend on what is being measured. It could be a skill, a talent, or an aptitude, to name a few. “Two of the primary criteria of evaluation in any measurement or observation are: 1. Whether we are measuring what we intend to measure.
2. Whether the same measurement process yields the same results” (QMSS e-lessons) Test-retest reliability would consist of comparing the results of the same test, given to the same group of people, on two separate occasions. This method is mostly used to measure things that remain fairly constant, such as intelligence or math abilities.
Inter-rater reliability would consist of having two different raters evaluate the same group of people on the same occasion and comparing the results of one rater to the other.
Internal consistency reliability is mainly used to measure how inter-correlated the measured items are. This reliability would consist of repeating, essentially the same question, worded...
