| Examining Correlations |
Examine the Correlation Matrix table. The correlation coefficient is a numerical measure that quantifies the strength of linear relationships. GPA, the grade point average, shows a correlation of 0.4365 with HSM, the high school math average. This is not surprising since you would expect the more successful computer science majors to have stronger quantitative skills.
GPA is not as strongly correlated with the other variables and shows a correlation of only 0.1145 with SATV. The verbal portion of the SAT exam does not measure the quantitative skills needed by computer science majors.
