Sample criteria
- Max sample size: The max size of panelists in the sample (0 = unlimited).
- Sample type: The sample type specifies how the sample is drawn from the finite population of panelists. Available types are: Random, Least recently invited, Least invited, and Least responded. Note that some of the sample types can be disabled if database in use does not support features needed for sample extraction.
Sample conditions
For each attribute in the panel the sample definition can include a sample condition. A sample condition specifies the value(s) for a panel attribute. Panelists with the same value(s) in his/her profile will match the condition. If all conditions in the sample definition are fulfilled by the values in the panelist's profile the panelist can be included in the sample, but might be left out if the number of panelists matching the conditions is bigger than the max sample size.
