In recent years I have found two editorials on the "correct" method to 
statistically analyze plate count data.  The first one said that the mean 
and the std. dev. should be determined from the arithmetic values of the 
data.  The second one said the data should be transformed to logs and 
then the mean and std. dev. should be calculated and then retransformed 
to scientific notation.  Are there any more opinions on how to deal with 
plate count data?  If anyone could suggest a text or article that deals 
with statistics for the analysis of plate count data, I would appreciate it.
Thank you!
