Application Notes

The statistics will be calculated for the lines/groups selected in the database.

The statistics for the X and Y channels are always included in the statistics summary if they are present in the database. The statistics calculated for the X and Y channels include the minimum and maximum values, total distance, and the number of valid points. They are calculated for each line separately and for the entire selected data set.

The statistics calculated for each additional channel include the minimum value, the maximum value, the arithmetic mean, the median, the mode, the standard deviation, the standard deviation of the first and fourth differences, the number of valid points, and the number of dummy values. These are calculated for each line separately and for the entire selected data set. Go to the Notes section of linked topic for further details.
