Statistical data
Fig. 6: Statistical data
Below the chart, there is an area (Fig. 6) showing statistical data:
Number of measured values belonging to a series of measurements, minimum and maximum
values, span (maximum - minimum), median, arithmetic average, standard deviation, standard error
and modal value.
Since there can be several modal values, these are shown in a dropdown menu which can be
unfolded with your mouse. The number within square brackets shows how often the modal value
occurs in the series of measurements.
The unit for the statistical data can be selected via the settings dialogue (Fig. 2).
You can select "MS/m" (megasiemens per metre) or "%IACS" (International Annealed Copper
Standard).
Series of measurements
On the left-hand side of the main window, there is an overview (Fig. 7) of all series of measurements
currently available in the software. The number of series of measurements is limited to 500.
Fig. 7: List of series of measurements
By selecting a series of measurements with a mouse click, the values of the series of measurements
are shown in a chart and the statistical values are re-calculated.
The identifiers of the series of measurements can be changed either with a double click or a right
click and selection of "Rename" (Fig. 8).
