A data collection strategy in which participants are signaled at random times throughout the day and record answers to researchers' questions is called:

Hybrid designs involving different kinds of field-lab experiments are becoming increasingly common. Describe these hybrid experimental designs and discuss their advantages and disadvantages.

A research sample in which participants are drawn from strata or categories in the same proportions as they are found in the larger population is:

Practice effects, or the effect of repeatedly testing participants over many years, is not a problem with longitudinal designs

A question less likely to be used with the experience sampling method would be:
