By default, Protobi shows the distribution and sample size (aka "basis") for all elements and the mean for all numeric elements. For example the following shows a distribution and mean for S2., "How long you have you been in practice?"
But you can choose which summary statistics you want to see for any question. Select the circle or square icon for any element and choose the menu item "Statistics..."
This will bring up a dialog that allows you to choose which statistics you want to see:
Below is an example with almost all options selected:
Use the boxes in the statistics dialog to specify topbox stats. Place the values you want to combine in brackets. You can use a colon followed by a specified name to give the stat a label. If unspecified, the label will be "1, or 2".
Statistics selections you make for a group will propagate to all children of the group (and recursively to their children).
