Answer to Question 1

a

Answer to Question 2

Test constructors may give the same test to the same group of students more than one time, to determine test-retest reliability. Test constructors may also wish to determine whether measurements from two or more slightly different versions of the same test are consistent with one another, that is, to find alternate-forms reliability. To determine this, they administer the different versions to a group of students and compare the results on each version.
Another way to calculate reliability is to compare students' performance on one part of the test with their performance on another part. This kind of internal-consistency reliability is often determined simply by dividing the test questions in half and comparing the two halves of the test, known as split-half reliability.
