I am not familiar with the survey carried out by the FCFA. Normally, at Statistics Canada, we carry out pilot projects before doing the survey. The pilot projects are qualitative tests during which we ask people specific questions to see if they understand. That helps us validate the wording of the questions.
Education is shown to be a striking example. There is several levels of education in the provinces, and different names are designated to describe the levels. We talk about daycares as often as we talk about child care centres, for example. Asking people if they understand the questions helps us make sure that people are clear on the concepts that we talk about.
