RockWorks | Borehole Manager | T-Data | Statistics
This program is used to calculate statistics for a single column of T-Data measurements in the current project, for all enabled boreholes. This can be a handy way to get a quick look at the range and distribution of values prior to, or after, modeling. This is the same tool that is present in the Utilities Stats | Univariate menu.
Feature Level: RockWorks Standard and higher

Step-by-Step Summary
Menu Options
- T-Data Track: Click to the right to select the track or column in the T-Data tab for which statistics are to be computed. The names displayed in the list will be pulled from the column headings. Expand this option to establish any source data filtering.
- Spatial (XYZ) Filtering: Insert a check in this box to activate a data filter based on spatial coordinates. Expand this heading to establish the filter settings. These tools filter the data that is passed to the statistics procedure.
- Filter based on Date/Time: Insert a check in this box to compute statistics for a specific date or range of dates. If you leave this un-checked the program will use all of the measurements, for all listed dates, in its computations. Expand this heading to access the Filter Options.
- Exact: Click in this button if you wish to enter a specific date (and time, if applicable) for the measurements to be processed. Click on the date displayed after the Date/Time Target to type or pick from the calendar the specific date. During statistics computations RockWorks will process the T-Data measurements for the selected track that fall on this date.
- Range: Click in this button if you prefer to enter a beginning and ending date to define the range of dates to be included in the report. Click on the dates displayed after the Starting and Ending prompts to type in or pick dates from the calendar. During statistics computations RockWorks will process the T-Data measurements for the selected track that fall within this date range.
- Filter Based on G-Values: Activate this option to filter the data based on the measured values, and expand the heading to establish the filter parameters. (More.)
- Resample at Regularly-Spaced Intervals: Check this box to resample the data. (More.)
- Create Filter / Sampling Report: If you've selected any filter/resampling options, this tool will create a summary report of the results. (More.)
- Titles: Here you can specify report titles.
- Primary: Click to the right to enter the text to be plotted as the primary title at the top of the Statistics Report. The text should be limited to 80 characters. If no title is desired, click on the Primary heading and delete any text that's displayed there.
- Secondary: Click to the right to enter the text to be plotted as the secondary title beneath the Primary Title at the top of the Statistics Report. The text should be limited to 80 characters. If no title is desired, click on the Secondary heading and delete any text that's displayed there.
Step-by-Step Summary
- Access the RockWorks Borehole Manager program tab.
- Enter/import your data into the Borehole Manager.
- Be sure the boreholes for which you wish to generate the statistical report are enabled.
- Select the T-Data | Statistics menu option.
- Enter the requested menu items, described above.
- Click the Process button to continue.
The program will read the selected track of data for the enabled boreholes, apply any requested filtering operations, and then compute the general statistics. The statistical summary will be displayed in a Text tab in the Options window.
- You can adjust any of the input options, and click the Process button again to create a new report.
From here you can print the information, copy it to the clipboard for pasting into another application, save the information on disk, etc.
The results will include the following calculated statistics:
- Population: The number of values the program found for the selected data which fell within the specified filtering range and which were included in the statistics calculations.
- Minimum Value: The minimum value for the data included within the calculations.
- Maximum Value: The maximum value for the data included within the calculations.
- Mean: The arithmetic average of the sample data, equaling the sum of the values divided by the number of measurements.
- Standard Deviation: A measurement that indicates the way in which the data is centered around its mean, equal to the positive square root of the variance of the sample.
- Standard Error: A measurement that indicates the variability that can be expected in the means computed for samples taken randomly from the same population.
- Median: The value that is in the middle of the frequency distribution of the data.
- Sum: The total of all data included within the calculations added together.
- Square Root of Sum: The arithmetic square root of the total of all data included within the calculations added together.
- Sum Squared: The value of the total of all data included within the calculations added together and multiplied by itself.
- Variance: The measured degree of difference between all data included within the calculations.
- Deleted Points: The number of measurements that were excluded from the calculations because they fell outside a specified filtering range.
- Statistical cutoff data, such as Mean + and - 1 Standard Deviation, 2 Standard Deviations, 3 Standard Deviations, and the populations represented within these groupings.
