Box and whisker plots display data through a box and whisker format. To create one, the data is first arranged from smallest to largest. The median is found as the middle number or average of the two middle numbers. Quartiles are determined by finding the median of the lower and upper halves of the data. The whiskers represent the smallest and largest values. A box and whisker plot is drawn with a number line, median line, quartile lines, and whiskers connecting the minimum and maximum dots. John Tukey invented the box and whisker plot in 1977 to visually display statistics.

2. How to get the data for a box- and
-whisker plot
 First arrange the numbers from smallest to
largest
 Next find the median by finding the middle
number of the data (If there are two add them
together and divide by two)
 Then we find the Quartile by finding the
median of the two haves of the data
 Lastly you need to find the whiskers which are
the smallest and the biggest number

3. How to set up a box an whisker
plot
 First make a number line that can fit your data
 Make a line to label the median
 Then make two more lines to label your two
quartiles
 To make your whiskers label the higest and
lowest number with dots
 Next label median, the two quartiles, and the
highest and lowest number
 Lastly connect all three lines to make a box.
 Also connect the two dots with a line to the box
