SeekTable can be used for survey or questionnaire results analysis as it can summarize data by answers, calculate percentages, cross-tabulate and compare subgroups. Finally, it can visualize results with various charts.
You can check these demos to get some understanding about what survery reports may be created with SeekTable:
How to perform survey results analysis:
Export survey data to CSV.
Upload CSV file into your SeekTable account (max 50Mb compressed).
If survey data is too large for upload you can import it into SQL database (or MongoDb) and configure it as a data source.
In survey analysis it is often to enough to get just mean (average) values; another important measure is median (or 50% quantile) which reflects a middle value.
You can configure median (or any quantile) measure in the following way:
Go to cube configuration form ("Edit Configuration" on the cube details view)
Add new measure
Choose "Quantile" type
Add a 1st parameter with name of CSV number column
Add a 2nd parameter if you want to specify quantile value (between 0.0 and 1.0). If this parameter is not specified 0.5-quantile is calculated (which is median).
