Competition
Analyzing the effectiveness of test preparation courses
This competition is designed to help you get started with DataCamp Competitions and familiarize yourself with how competitions work. Your best friend is an administrator at a large school. The school makes every student take year-end math, reading, and writing exams. Since you have recently learned data manipulation and plotting, you suggest helping your friend analyze the score results. The school's principal wants to know if test preparation courses are helpful. She also wants to explore the effect of parental education level on test scores.
