Mr. Ma hired expert test-takers in Manhattan, who used false names to register for the Graduate Management Admission Test, which most business schools require of applicants; the Graduate Record Examinations, a test for graduate school, and the Test of English as a Foreign Language.
Data for the analysis come from a battery of standardized examinations, including medical examinations, a test of intellectual capacity, and a test of coping in relation to stress.
To evaluate the difference in values between the initial examination and subsequent examinations, a paired t-test was used.
The examinations test a student's general analytic ability in economics and knowledge of two fields chosen by the student.
Patients were interviewed at these times as well undergoing a physical examination, pulmonary function testing, a 6-min walk test and quality of life evaluation.
Evaluation can take more than a year, and generally includes interviews, written and oral exams, physical and psychological examinations, a fitness test, a polygraph exam, drug testing, credit checks and an extensive background investigation.
Two hundred participants were further selected for a second re-examination (test-retest validity) 14 days after the first application.
The pattern existed on five different tests — two regents examinations, a middle school test and two grade school tests.
Also, for both screening examinations, an inconclusive test in the actual year may make it necessary for a follow-up control screening examination in the next year.
