A team of American researchers studying Educational Psychology were interested in investigating the use of SAT scores
Question:
A team of American researchers studying Educational Psychology were interested in investigating the use of SAT scores (the SAT is a standardized test used for college admissions in the United States) when determining admission standards to undergraduate programs. The researchers sampled 224 undergraduate admissions from the current year's graduating class in Psychology. Admission criteria, including SAT-Math score (scores on the math component of the SAT college admissions test) and SAT-Verbal score (scores on the verbal component of the SAT college admissions test), were considered (all measured as continuous variables). The team of researchers wanted to determine if there was a relationship between undergraduate performance (measured by cumulative GPA) and each type of admission criteria (SAT-Math and SAT-Verbal). Please use the data below to answer this question.
