The test was given in less time (16 minutes) instead of 21 minutes. Three variables were analyzed: Speed, Level, Power.
College students with no specific description other than they were in R.O.T.C.
The main dependent measure was the Otis Self-Administering Test. Three criterion variables were used:
ò The Army Alpha Revised Form Five with the following measures collected: number of items correct in limited time and unlimited time and the time taken to complete the test
ò The College Aptitude Test
ò Honor point ratio
For the College Aptitude Test, level had greater validity with power. Power was found to have greater validity with the criterion of grades than speed or level. Speed and level in combination provide a significant contribution to power. Speed and level are independent. When measured in groups, the validity of level and power decreases.
