Statistics

AccuGlobe can perform a statistical analysis on any column. Numeric column data will provide more results, such as the mean and sum. The values of numeric fields are displayed in blue text. To run statistical analysis on a column follow the steps below:

1. Move the mouse over the column field names.
2. Click the right mouse button.
3. From the popup menu, select Statistics
4. The statistical analysis will appear with the ability to copy to the clipboard. This process may take some time for large datasets.
5. The analysis will consist of:
   
   • Maximum Value (numeric fields only). This is the highest value.
   • Minimum Value (numeric fields only). This is the lowest value.
   • Range Value (numeric fields only). This is the difference between the lowest and highest values.
   • Sum Value (numeric fields only). This is the total summed value of all features.
   • Average Value (numeric fields only). This is the mean value.
   • Unique Values. TODO
   • Non-Unique Values. TODO
   • Feature Count Value (numeric fields only)

Selecting Features

It is possible to select features from the attribute table. Follow the steps below:

1. Hold down the Shift (to append a range of features to the selection subset) or Control keys (to append multiple discrete features to the selection subset). Without holding down either of these buttons a new selection subset will be created.
2. Move the mouse over row to be selected.
3. Click with the left mouse button.
4. Depending on whether shift, control or no keys where pressed the new selection will now be displayed.

All selected features will have a yellow background, all non-selected features will have a white background.
