 ### Choosing The Algorithm For Computing Quartiles
 
-By default, quartiles for box plots are computed using a linear algorithm method (see #10 listed on http://www.amstat.org/publications/jse/v14n3/langford.html for more details). However, you can also choose to use an `exclusive` or an `inclusive` algorithm to compute quartiles.

-The *exclusive* algorithm uses the median to divide the ordered dataset into two halves. If the sample is odd, it does not includes the median in either half. Q1 is then the median of the lower half and Q3 is the median of the upper half.
