It goes on to point out the advantages of this item type: Since only two options are possible, alternative-response items are generally shorter, and, therefore, require less reading time. Reliability of a test has implications in measuring a persons personality traits which do not change with time and not in knowledge and skills which change with time.

Owing to the competitive advantages of fast response speed, large pushing force, high reliability, and high precision, the permanent magnet linear synchronous motor (PMLSM) has played an increasingly vital role in various high-speed and high-precision control systems. Suppose the same researcher conducts the two different forms of tests on the same topic and the same students. Memory, practice, carryover effects and recall factors are minimised and they do not effect the scores. Board: Reliability is a measure of whether something stays the same, i.e. For example, if the professor gives out test A to all students at the beginning of the semester and then gives out the same test A at the end of the semester, the students may simply memorize the questions and answers from the first test.
