§ 65.29 – What steps should I take if I fail to collect the sample data from a particular unit?

(a)    You may fail to collect the required sample data from any particular unit in your sample:

(1)   The unit may be canceled for a variety of operational reasons.

(2)   The ride checker(s) may fail to show up for the unit.

(3)   The ride checker(s) may fail to collect the data.

(b)   You must replace the missed unit as soon as possible on the same type of service days.

(c)    For period-based sampling:

(1)   If the rest of the sampling period (a week, a month, or a quarter) has at least one service day of the same type as the missed service unit, select one service unit from the next service day of the same type.  For example, if the missed service unit is on the second Monday of a month and your sampling is monthly, you should get a replacement unit from the third Monday of the month.

(2)   If the rest of the sampling period does not have any service day of the same type left, select one service unit from the first service day of the same type during the next sampling period.  For example, if the missed service unit is on a Monday and your sampling is weekly, you should get a replacement unit from the next Monday. 

(d)   For interval-based sampling:

(1)   If the rest of the report year has at least one service day of the same type as the missed service unit, select one service unit from the next service day of the same type.

(2)   If the rest of the report year does not have any service day of the same type left, select one service unit from the next day of service.

(e)    The replacement unit must be selected at random in all cases.
