Document Summary
Tests that are designed to assess a person"s previous learning in a specific academic area. Key differentiator: the extent to which specific training influences performance. Sat i - general measure of verbal and mathematical reasoning. Sat ii specific versions (e. g. , world history, chemistry, physics, etc. ) Revised each year because previous forms are publically accessible. Predictive validity with college performance ~ . 40 - . 60. Regularly assessed for potential biases and keeping content current. Sat mean = 500, standard deviation = 100. Sat verbal mean = 420, sat mathematical mean = 480. Sat mean = 500, standard deviation = 110. Range restriction because it is used as a selection tool. Scores represent relative performance to a fixed reference group; given a percentile rank. Raw score is the number of correctly answered questions -1/4 of the questions answered incorrectly. Tests the reading, writing, and math skills students should have learned by the end of grade 3.
