Whats New in This Release

Statistics Calculator:
· Implemented a simple Statistics Calculator (Utilities > Statistics Calculator). The initial release contains
· procedures for the basic statistics of ungrouped data, the basic statistics of grouped data and several
· types of 2-variable regression (linear, logarithmic, exponential, power, quadratic). Depending on user
· feedback, other statistical procedures will be implemented in the future.
· Data plotting capabilities are also available – Box plots, XY plots and regression line plots.
· Data files must be plain text files in CSV format, although using a comma as the field separator is not
· recommended. The default file extension is .sta. A simple Data Editor is provided for creating such
· files but any text editor or spreadsheet program may be used.
· For further information, consult the Statistics Calculator section later in this document.

Average Speed Based Calculations:
· Added a new utility (Utilities > Average Speed) for calculating any one of distance ...
