(a) I chose the data set link 2007 Advanced Placement (AP) Exam Scores by Discipline.
(b) The data set contains 2,533,431 AP Examinations taken by 1,464,254 students from 16,464 secondary schools. It shows the subject of the Examination, the Examinations grade, the number of students who received either a 1,2,3,4, or 5. The Mean of the grade and it's standard deviation.
The purpose of this data is to evaluate the performance for each grade level, type of school, or geographic location.
(c) Examinations of foreign language tend to have a higher Mean Grade than the other Examinations. Why do some students perform higher on foreign language examinations?
I believe that most of the students who take foreign language examinations already have a strong foundation in the language before taking the AP class. The students might speak the language at home or know it as their first language.
