However, intelligence typically involves an individual’s ability to learn from experience and adapt to the environment in which they live. I believe that the construct of intelligence should encompass an individual’s ability to effectively communicate in both written and verbal form, to think logically, and to express creativity. Two intelligence tests in which I recently had the opportunity to take and score included the Shipley Institute of Living Scale-2 and the Wonderlic Personnel Test. The purpose of this paper is to objectively evaluate each test and the subsequent results that I obtained in detail. In evaluating the Shipley-2 and the Wonderlic, I will also methodically describe the psychometric properties involved, explain the potential sources of unsystematic error related to each test, and compare my scores to two separate external criterion measures.
Test Descriptions The Shipley-2 and the Wonderlic were each designed to be short group intelligence tests capable of assessing specific areas of intelligence. The Shipley-2 can be complete in 22 minutes, while the Wonderlic can be completed in 12 minutes. Also, the Shipley-2 is designed for an age population ranging from 7 years to 89 years, while the Wonderlic is designed strictly for the adult population. The original purpose of the Shipley-2 was to measure intellectual deterioration in…
