This review of Data Desk Professional, a statistical software package for Macintosh microcomputers, includes information on: (1) cost and the amount and allocation of memory; (2) usability (documentation quality, ease of use); (3) running programs; (4) program output (quality of graphics); (5) accuracy; and (6) user services. In conclusion, it is noted that the program is oriented toward an exploratory data analysis (EDA) approach, which encourages an open-ended analysis of data, and that the user is able to examine a data file in a very flexible and thorough fashion. In terms of traditional statistical analysis, however, Data Desk has a number of clear deficiencies, in that some of the programs are inflexible and incomplete. (GL)
