The test itself consists of 160 multiple choice questions that must be answered in five hours (the number of questions and the test length may vary due to the exam being changed by the ASQ).

As a practical matter, the algorithm is generally programmed to have a minimum and a maximum test length (or a minimum and maximum administration time).

The best procedure in such situations is to use several specimens of different test length, continuing the study until uniform results are obtained.

This process repeats until the examinee is classified or another ending point is satisfied (all items in the bank have been administered, or a maximum test length is reached).

Atom takes almost twice as long to finish its Mozilla test, but tossing a WME job on top of the browser only extends the test length by about 33 percent.

The test length varies from patient to patient as bowel motility is highly variable.

The test length increased again to an amazing 17 minutes.

This explains that number of the failures doesn't depends on test lengths.

The Spearman-Brown prediction formula, also known as the Spearman-Brown prophecy formula, is a formula relating psychometric reliability to test length and used by psychometricians to predict the reliability of a test after changing the test length.

This halves reliability estimate is then stepped up to the full test length using the Spearman-Brown prediction formula.
