Exploring One–Variable Data
Which graphical representation shows the five-number summary including minimum, Q1, median, Q3, and maximum?
When comparing two distributions with similar shapes and spreads, which measure is most reliable for determining if one distribution typically has higher values?
In examining parallel box plots measuring test scores from multiple classes, what indicator might suggest that one class's performance is more inconsistent than others even if their medians are identical?
The stem-and-leaf plots below represent the scores of two groups of students, Group P and Group Q, on a math test. Use the plots to compare the score distributions of the two groups.
