A survey was taken of students at a large university in the fall of 2003; among other things, students were asked to report how many credits they were taking and their SAT scores. There is a positive correlation between number of credits taken and Math SAT score. When outliers whose number of credits is below 12 are omitted, there is no more substantial correlation between number of credits taken and Math SAT score. If we want to see if Math SAT scores are lower for part-time students compared to full-time students, what display could be used? A histogram, a pie chart, a bar graph, side-by-side box plots, a stem plot, a scatterplot
