§ 53.05 – Do interval-based sampling plans have any special requirement for the sample data used in developing them?

(a)    Yes, the sample data must have 2 or more service units for every sample day.

(b)   If you sampled 3 one-way bus trips every 2nd day with an annual total sample of 549 trips during your last sampling year, your sample data would meet this requirement.  If you have identified and corrected errors in your sample data, you may use them for developing interval-based sampling plans with the template.
