ht which data points are to be the focus of manipulation,
analyses, or graphing. If the user finds a requested statistical procedure
produces a "cannot divide by zero" notice, it is certain that no entered
data were highlighted. Oops; no problem. Simply click off the requester,
highlight data, and go again. Viola, results!
Data can be entered directly from the keyboard into the editor or from
a comma, tab, or space delimited ASCII file with ease. The latter is
helpful if one wishes to enter data by rows instead of columns, though the
former can be accomplished indirectly with a simple transposition within SSG
itself. This is important because it is often easier to enter all data from
a single subject or respondent file or questionnaire at one time, across
variables (columns), instead of entering all persons' responses for one
variable, followed by the next variable, etc. Unlike other statistics
programs, it is not necessary to know the number of rows or columns when
loading a data file, nor are any conversion processes required. SSG just
loads the data and displays it in the editor, awaiting ones pleasure for
manipulation, analyses, and display. For anyone who has fought conversion
programs this capability may make SSG worth the price of admission.
The editor also includes a variety of tools to copy, cut, paste, merge,
convert, and sort data before getting into the business of analysis. These
are powerful tools, well documented, and demonstrated in the manual. One
drawback which the author says will be addressed in the next version is the
need that data points be contiguous in the editor for them to be highlightedåh?????å╠?/.╠⌐4⌐?
and analyzed. Though rather inconvenient, the copy tool offers a fairly
simple means to work around this limitation. The exact method is intuitive
but explained in the manual, nevertheless.
Statistical analyses can be performed interactively on a given data set
or by batch file when repetitive work is required. Both processes are
explained in clear detail. The rang
