A researcher is pondering what survey mode to use for a client that markets a home security system.

The system consists of tiny motion sensors that are pressed onto all of the windows and doors. Once connected with Amazon Echo, Google Home, Apple HomePod, or another digital assistant, when a sensor is activated, the system turns on lights, emits a warning sound, activates webcams, and texts the owner, depending on what devices and capabilities are linked.

The client wants to know how many homeowners in the United States are aware of the system, what they think of it, and how likely they are to buy it in the coming year. Which consideration factors are positive, and which are negative for each of the following survey modes:

(a) in-home interview;

(b) mall intercept,

(c) online survey;

(d) drop-off survey; and

(e) CATI survey?
