Box Plots g A boxplot is a graph depicting a group of numerical data through its five-number summary: the smallest value, lower quartile (Q1), median (Q2), upper quartile (Q3), and largest value. The left side The right side The end of of the of the The end of this whisker This line rectangle rectangle this whisker shows the shows the shows the shows the shows the smallest value median lower upper largest value quartile quartile The width of the box shows the interquartile range (IQR) To construct a box plot Step 1: Order the data list and find the five-number summary for the data. Step 2: Draw a horizontal axis and place the scale on the axis. The scale should start on or below the minimum value and end on or above the maximum data value. Step 3: Locate the lowest data value, Q1, the median, Q3, and the highest data value. Draw a box whose vertical lines align with Q1 and Q3. Draw a vertical line in the box that aligns with the median. Lastly, draw a horizontal line, or whisker, that begins with the lowest data value and ends at the left side of the box and another horizontal line the begins with the right side of the box and ends with the highest data value. Study the box plots below for trends in the data. Complete the Five-Number Summaries and IQR for each city: City Min Q1 Q2 Q3 Max IQR Tucson Seattle Boston Locate each city on the map below. Does each city’s location explain the difference in its box plot values?
