Bulletin presentation for Survey Results

1 Requirements

• Stacked bar chart: One rectangular shape stretching horizontally. Only one rectangle per question covering all answer options, full form represents 100%. Needs very little screen estate.
• Column chart: For each answer option there is one rectangular shape stretching vertically. Needs a lot of screen estate.
• Pie Chart: For each answer option that was selected at least once, there is one piece of pie. All pieces of pie forming a circle. Needs a lot of screen estate.
• Line charts are ruled out since they require a lot of data of a high type of scale which is typically not to be expected.

 
The following table lists what chart would be suitable for what question type in general

Question Type	Options for charts
Multiple Choice (Single Response)	Stacked bar chart, column chart, pie chart
Multiple Choice (Multiple Response)	Stacked bar chart, column chart, pie chart
Matrix Question	Stacked bar chart
Metric Question	Column Chart or no chart
Essay	No chart

1.1 Status and Mock-Ups per Questions Type

The concept of Bulletings in Surveys is based on the KS-Entry: Bulletin.

1.1.1 Essay Question 

The essay question has no chart. This should stay this way.

1.1.2 Matrix Question

In ILIAS 5.1 the matrix report comes with one entry per row which is quiet disturbing. All rows of a matrix should be reported within one single Bulletin, there should be no longer be one Bulletin per row.

Since multiple rows of a matrix are to be displayed in one single report it has to be a Stacked bar chart, since this allows displaying data with little space.  Pie charts would eat up way to much space as would columns, too. 

1.1.3 Multiple Choice Question (Multiple Response)

This question type could be done either as stacked bar chart, column chart or pie chart.

• Stacked bar charts are most economical concerning the space they cover but they are not as intuitive to read and compare the relative sizes of their individual segments to each other. 
• Columns charts are the dullest but most intellgible option. 
• The pie chart consumes the most space of these options. 

1.1.4 Multiple Choice Question (Single Response)

Same as Multiple Response

1.1.5 Metric Question

This has to be a column chart or no chart.

1.2 The Sub-Tab "Details" in the Results-Tab

Toolbar 
Another part of the toolbar should allow for configuring the reports. One can select the figures to be included and the type of presentation.

3 Discussion

Seiler, Yvonne [yvseiler] 29. march 2016: We highly appreciate this improvements. The charts and tables look much prettier and easier to decode.
Our thoughts about some aspects from above:

• 1.2 The Sub-Tab "Details" in the Results-Tab > Toolbar: We would prefer another order for the "Presentation" dropdown: Both | Table | Chart (Both = default). Because at the moment charts are visible per default and mostly they are easier to scan the results than a table.
• Report Card: We like the report card and block version. Please consider also the PDF-Export version of this new survey result views.
• Charts: Have you already thought about accessibility? In the version ILIAS 5.0 you have numbers to merge the stacks with the answers (f.e. 1, 2,...). Now you only would have colors which would be a problem for color blind people or if you made a black-and-white print. Would there be a hint for such handicapes?
  • I know this problem also appears at the "poll" tool....
• Spider Chart: update 23.05.2016 yvseiler: Discussion with Alexandra Tödt changed my mind about spider charts. Because they aren't easy to interprete I would change my comment below: Matrix questions doesn't need a spider chart. In 360° Feedback you have a Spider Chart for the matrix question. Did you already thought about it, if spider chart would be interesting for the Matrix Question (SC)? => because it's already a feature in survey. But I do not know if this would be really a good idea - just a train of thought. 

JourFixe, ILIAS [jourfixe], June 20, 2016: We highly appreciate this suggestion and schedule the feature for 5.2.

, 23 Aug 2016: This feature has been implemented as described above.
