A H.S. algebra teacher would like to more accurately identify students who should be enrolled in Algebra I rather than pre-Algebra. Currently, the school district uses the teacher recommendation (based on student grades), as a mechanism for identifying which students should be placed in Algebra I. There have been many students misplaced in both courses over the last three years. The teacher learned that The Iowa Algebra Aptitude Test (IAAT) is often recommended as a screener for placing students into these courses. The H.S. teacher would like to determine the relationship between student grades and performance on the IAAT. If the relationship were strong the teacher would then conduct a study to see how well the IAAT would predict final exam scores in Algebra I and Pre-Algebra courses. This information would confirm the use of the IAAT as one method for placing students. What analysis should the teacher conduct to determine how well the IAAT will predict student final exam scores?
