Thank you for your interest in the questionnaire concerning the concept of roles of variables. The questionnaire has been closed and this page is now inactive. You can browse the questionnaire and get feedback in the second phase but you cannot submit your results anymore.
The original page starts here:
There are 6 programs on this web page. The instructions are similar to those of the previous phase, except that you click on Submit when you have completed the selection of roles for all variables in all programs. Your selections will then be automatically included in the research data base.
In this phase you may select "some other role" if you think that the roles that have been presented do not adequately characterize a variable. If you choose "some other role" or if you were very unsure about your selection, please write a short explanation of what you think characterizes the role of these variables.
You must select a role for each variable; it is possible to select "I do not know", but we would prefer that you do not do so. If you really have to use it, please explain what problems you had with the variable.
