A sample of typical undergraduate students is very likely to have a range of GPAs from 1.0 to 4.0, whereas graduate students are often required to have good grades (e.g., from 3.0 to 4.0). Please explain what influence these two different ranges of GPA would have on any correlations calculated on these two separate groups of students.
