Doubling dilution vs serial dilution

Not according to http://www.google.ie/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CCEQFjAA&url=http%3A%2F%2Fwww.austincc.edu%2Fmlt%2Fclin1%2Fser_SerialDilutions.ppt&ei=JRAsVJD9J-Ke7gbDm4CIBw&usg=AFQjCNEBU8TDlOZ8TJGB7vMxqKOFYNuubw&sig2=vzy24CmRP8BKE4ngwaYteQ&bvm=bv.76477589,d.ZGU . The wiki states that a serial dilution are the stepwise dilution of a substance in solution. Whereas doubling dilutions is the stepwise dilution of the substance in solution by 1/2. So doubling dilutions are a type of serial dilution. The word serial means of or forming a series. So serial dilutions are done in a particular series and everything can be in a series. So any dilution.

Hi, those are not the same:

 

Doubling dilution is a serial dilution effected so that the concentration in each tube of the particular cell, substance, etc. of interest is half that in the preceding tube of the series.

 

Whereas serial dilution is the stepwise dilution of a substance in solution. Usually the dilution factor at each step is constant, resulting in a geometric progression of the concentration in a logaritmic fashion. A ten-fold serial dilution could be 1 M, 0.1 M, 0.01 M, 0.001 M.
