Creating box plots

The first instance of  is under the Probability and statistics Math Mission. This exercise teaches how to create box-whisker plots (also called boxplots in some contexts).

Types of Problems
There is one type of problem in this exercise:


 * 1) Make the box-whisker plot: This problem provides a list of several numbers. The student is asked to create a box-whisker plot from the available data using the manipulative.Bwp.png

Strategies
This exercise is easy to get accuracy badges as long as you know how to calculate the five-number summary. It is medium to get speed badges especially if you use the manipulative to put the numbers in numerical order.
 * 1) The five-number summary consists of the Minimum, the First Quartile, the Median, the Third Quartile, and the Maximum.
 * 2) The First Quartile is the median of the lowest half of numbers and the Third Quartile is the median of the upper-half of data values.
 * 3) Khan Academy accepts the calculation of quartiles where you remove the median when there are an odd number of data points.
 * 4) You do not need to put the numbers in order to get the right answer, it is not part of the solution, only the plot.
 * 5) The TI-83/84 level calculator can be used by quickly writing the data values into L1 and performing 1-VarStats on L1 (the five-number summary is found by scrolling downward).
