Aresearcher develops a 20-question test to measure anxiety and administers it to a group of participants. to evaluate the reliability of the test, the researcher computes a score for the first 10 questions and a score for the last 10 questions for each participant and then computes the correlation between the two scores. what is the researcher measuring
a. split-half reliability
b. internal reliability
c. test-retest reliability
d. inter-rater reliability

Option (A) is correct.

Explanation:

In accordance with the split-half reliability, a study or test for a particular knowledge domain is divided into 2 parts and therefore both parts are given to a single group of individuals at a particular time. The scores received from these parts of test are somewhat correlated.

Split-half is known as an evaluation of consistency(internal) i.e. how well do components tend to contribute to variables which are being measured.
