A study by Grimstvedt et al. (2010) of the effects of signage on stair use in university buildings examined the effect of placing signs encouraging stair use near elevators. Based on their design, Blake is designing a study for her campus. The initial part of the study will be a month-long measuring of elevator and stair use in four buildings on the campus. This will be followed by the treatment, which is the simultaneous posting of signs at each of the four locations. Elevator and stair use will then be measured for another month. Which type of design is this? A. stable baseline
B. multiple baseline
C. matched groups
D. interrupted time-series

stable-baseline

Explanation:

In simple words, Design from a solid foundation. A small model wherein an investigator tracks behavior for a prolonged baseline time before starting a medication or other interference; if behavior is consistent over the retrospective, the investigator may be more confident in the operations efficacy.

Thus, from the above explanation we can conclude that the correct answer is stable baseline.
