Adaptive Questionnaire Based on a Target Variable
The adaptive questionnaire allows an automatic and dynamic organization of the monitors while taking into account what information is being contributed to the knowledge of the target variable and the corresponding of the questions. The target monitor appears with a pink background at the top of the list, followed by the monitors ranked by their relevance.
The monitors of the observed variables appear at the end of the list (grayed) in the order of observation. The last observed variable then appears just after the last most relevant variable. It is possible to remove an observation or to change the observed value by double-clicking on the monitor. It is also possible to observe a variable that does not appear in the proposed list by monitoring it manually.
The are never proposed to the user.
Adaptive Questionnaire Based on a Particular State of the Target Variable
This questionnaire is similar to the previous one but the questions' worth is measured on the knowledge of a particular value of the target variable, and not on the global knowledge of that variable. When the target is a variable only having two states, then these two questionnaires are equivalent.
