SPSS Strengths

  • Easily opens data from other programs such as Excel and SAS.
  • Variable view screen allows for quick overview of file contents and allows for easy modifications of names, formats, labels, and variable order.
  • Having all data information in a single file allows sharing files on a project to be very easy.
  • Point-and-click menus do not require memorizing syntax for majority of procedures.
  • Many procedures can be expanded beyond the menu options in syntax.
  • Split-file command allows all output to be replicated for various groups through a single command.
  • Journal file tracks all commands used for life of program, with good resources to find code accidentally deleted.
