The Statistics artefact provides a statistical summary of the data present in a project. Statistics will be computed for the selected properties, and this can be combined with a palette to produce grouped (stratified) statistics. A sample set can be applied to restrict the calculations to a subset of the data. This provides a means to effectively summarise and extract trends from data sets.

How to use in practice

p:IGI+ Statistics

Stats table update


A statistical summary of the data present in a project is possible. Data properties from the p:IGI+ property model can be combined with a single Palette (Colour, Size or Shape) and/or a single Sample set (either Dynamic or Static) and/or a single Well Sample set (if not already an Expression in the sample set Query) to provide a means to effectively summarise and extract the significance from large data sets.

The Statistics artefact reports:

Properties to be included in the statistical summary can be chosen through the Add/Remove Properties link at the bottom of the dialogue window and the subsequent use of the standard Property Selector. When using properties which have associated indicators [Gas and Molecular] use the  Bulk Update Properties link to interchange between different indicator groups.

Any application of palettes, samples sets or well sample sets to a statistics artefact will see the summary data revise itself automatically. A progress bar is provided where large numbers of properties or groupings are present.

When a palette is applied to the statistical dialogue the data is automatically sub-divided by individual palette entry - this provides you with an easy way to group or stratify your statistics. Once grouped the data display can be ordered by either:

An alternative to hiding all rows with no data, is to control the groupings which are visible through the palette (often called 'stratified statistics'). This is achieved by opening the applied palette from the statistics window (double click the appropriate icon in the top right of the dialogue window) and hiding the palette entries not wished to be seen.

For easy reporting, a record of the statistical summary can be copied to the clipboard and transferred to other applications.

In p:IGI+ the user can create as many occurrences of a statistical summary as they wish. In addition created summaries can be saved externally as an artefact template through Right Click --> Export As Template... for use in other projects or to send to other users.

From version 2.2 it is possible to customise the statistics shown on the artefact using the Edit the statistics shown... link.
