      This paper  repeats part of  the analysis performed in  the 1995
      paper   ``Experimental  evaluation   in   computer  science:   A
      quantitative study'' by Tichy  and collaborators, for 147 papers
      randomly selected from the ACM,  published in the year 2005. The
      papers published  in 2005 are  classified in the  following way:
      4\%  theory,  17\% empirical,  4.7\%  hypothesis testing,  3.4\%
      other,  and  70\% design  and  modeling  (using  the 1995  paper
      categories). Within  the design and modeling class,  33\% of the
      papers have  no evaluation. The  numbers of the 2005  sample are
      very similar to the original  figures for the 1995 sample, which
      shows   that  Computer  Science   research  has   not  increased
      significantly its empirical or experimental component.
