Show N size for a group of elements

Updated at 2020-07-15 18:50:48 UTC

In compacted groups, N sizes aren't visible unless you press the triangles next to child elements. 

Protobi compacted group Q2 showing collapsed child elements. Group header displays 'Q2' with square icon, title 'Which car brands have you heard of?'. Seven child elements listed below with triangles indicating they can be expanded: Audi, BMW, Honda, Mercedes, Nissan, Toyota, Volkswagen. No N size shown at parent level.

However there is a way to show an N size for a parent group, (e.g. Q2), by telling it where to source an N size from.

1. In Q2's context menu choose "More properties...". From there, change type from "empty" to "default. 

2. Choose a child element from which to get the N size. Put the child element's key into field. 

Protobi More Properties dialog for Q2 showing configuration fields. Dialog displays element type dropdown changed from 'empty' to 'default', and 'field' input showing 'q2_1' to specify source for N size. Other properties visible include key, type, title, and various options.

3. Go back to the group's context menu and choose "Statistics...". Uncheck all except "Basis".

Result

After making the changes above, Q2 will display an N size in the parent element. 

Protobi compacted group Q2 showing N size at parent level. Group header displays 'Q2', title 'Which car brands have you heard of?', and now shows 'N=100' statistic. Seven child elements still listed below: Audi, BMW, Honda, Mercedes, Nissan, Toyota, Volkswagen in collapsed state.
