Question Randomization Engine

The Question Randomization Engine is TG’s test randomization utility. It enables the author to apply a range of randomization options to a test. These settings can define the number, order and grouping of questions presented to the test taker. The TQB refers only to the set of "x" questions making up a specific test. This set of questions may have been created manually, cut-and-pasted from a text editor, imported from one or more question banks or by using TG’s Test Wizard.

Uses

Best Practices

We recommend experimenting with these options. Create one or more sample tests and try out the various randomization settings before applying them to your final test. This includes opening and examining the CPR test’s TQB settings (see below). Once you decide on a TQB setting and publish your test. Do not modify these settings once you publish your test and have real test data. Doing so corrupts your test results.

Some TQB settings should not be used if, for example, you need to use some of the Analysis Reports. This is because all of your test takers may not get all of the same questions or subjects. Exceptions include TG Web users. These users have access to the database and can generate Sql queries and/or generate custom reports. Please contact us for more details.

CPR Test – a randomization example

Your installation of Test Generator includes a Sample Class and two tests. The CPR test uses the randomization utility. Its 50 questions make up the CPR test’s question bank.

If you open the CPR test and select Test Settings > Section Properties > Randomization, notice the test author selected the Bank Type, Random Questions and type in 20 in the field below the instruction, "Questions: Select X questions from the set of questions."

TQB Options

None

If selected, all the questions are asked in the order they appear in the Test Editing Summary window.

Random Questions

If selected, the Test Creator must choose how many of the questions should be asked each time the test is taken. When a test taker takes the test, the program randomly selects the given number of questions from all the questions in the test.

Random Subjects

If selected, the Test Creator must choose how many of the test subjects should be asked each time the test is taken. All the questions from the randomly selected subjects are asked, but none of the questions from the non-selected subjects are asked.

Question-Subject 1

If selected, the Test Creator must choose how many random questions should be asked from each subject. That number of questions is asked from each subject on the test.

Question-Subject 2

If selected, the Test Creator must choose how many questions should be asked and from how many subjects. The specified number of questions is randomly selected from each of the specified number of subjects, which are also randomly selected.

Question-Subject 3

If selected, the Test Creator must choose how many random questions should be asked from each subject individually. (e.g., 15 from Subject X, 9 from Subject Y, and 13 from Subject Z.)

Note: The dialog box in the lower right of the Question Bank window contains important information about how Question Bank options may affect Test Scoring.

Note: The Random Subjects, Question-Subject 1, and Question-Subject 2 Bank Types have an Include questions with no subject in the random selection check box. If this box is checked, questions without a subject are treated as belonging to their own, separate subject. If this box is not checked, these questions are ignored.

Note: At the bottom of the Question Bank window, there is an Ask questions randomly check box. If this box is checked, randomly selected questions are asked in random order. If it is not checked, the randomized questions are presented in ascending order. (For example, if questions 3, 5, and 8 are selected randomly, question 3 is asked first, then 5, and then 8.)
