Regardless of the research modes selected including telephone only, on-line only, mail-only, or any mixture of those modes, the survey sampling process is the same. First, the target population is determined (i.e., adult Canadians, recent PSE graduates, etc.) and a population analysis with Census 2006/11 data is conducted. Second, a random sample (probability sampling) from the sampling frame (taking into account composite weighting features that balance the sample according to a propensity to respond) is taken. Third, the survey goes to field, where, regardless of mode, multiple contacts are attempted in order to bolster response rates.
Once the data collection process is complete, results are analyzed and, if necessary, rim-weighting is applied to the data tables (and delivered in the data file).
