According to the author a test is reliable if...

• The test measures what is supposed to measure.

• the test is neither too long nor too difficult.

• the test does not have any content that wasn't taught specifically in the classroom.

• if students get similar scores on the test regardless of the day when they take it.

The reliability coefficient is...

• A number that indicates the degree of validity the test has.

• A number that indicate how much we can trust in a test.

• A number indicating the amount of ideal items in a test.

• A number that indicates we can't trust a test.

In the split half method...

• The students take one half of the test one day, the other half another day and then are marked and marks are compared to measure reliability.

• The class group is divided in two and they take two different versions of the same test.

• Students decide what half of the test to do and are scored on it. Then results are compared to measure reliability.

• Subjects take the test in the usual way, but each subject is given two scores, one for each half of the exam. The two scores are compared.

One way of making tests more reliable is...

• Including lots of objective multiple choice items.

• Include as many items as possible on the test.

• Including a lot of items without right or wrong answers.

• Including the most important structures and contents.
