Parallel Box-and-Whisker Plots (HSC SSCE Mathematics Standard): Flashcards

Graphical display of data showing five key statistics

Min, $Q_1$, median ($Q_2$), $Q_3$, max

Point where 25% of data falls below

Point where 75% of data falls below

Middle value dividing data into two equal halves

Middle 50% of data, from $Q_1$ to $Q_3$

Lines extending from box to extreme values (min & max)

Two or more box plots aligned on same scale for comparison

Greater variability in central data

Must be drawn on same scale
