A questionnaire is a method for collecting data that can come from many
sources such as observations, telephone interviews or documentary
sources. Whatever the source of data is, the questionnaire provides a
framework of questions that facilitate researcher's work. A manual
approach for collecting data using questionnaire presents some
limitations and introduces several sources of errors. A second issue
regards the statistical and data mining of data that often is conducted
using different tools than the questionnaire system, which may introduce
errors in the analysis pipeline. For instance, common methods applied to
data set concern the normality test, the association and correlation
discovery, linear regression, classification and clustering. Usually
this analysis is performed using external tools, often not free, such as
SPSS, SAS, STATA, Weka, or Clementine.
We present a web-based software system, to automatize the analysis
pipeline and to support researchers involved in the collection of
questionnaire data, such as in epidemiology, aiming to reduce the errors
listed above and including some basic functions to conduct statistical
analysis on collected data. Our system allows researchers to create
questionnaires, adding sections and structured questions. It provides a
preview of the questionnaire, the exportation of saved data into
statistical software compatible formats, or it permits to analyze them
directly applying statistical methods and common data mining techniques
from the main interface.
