Sight Distance and Reaction Time. Sight Distance. Sight distance means the distance from which you can see and identify a hazard. You often see an object before youâre able to identify it as a hazard. If the stopping distance to an object is greater than the sight distance, youâre in danger of hitting the object.
The major methodology of this approach is the single-case experiment, or N = 1 design. Although there are many kinds of N = 1 designs, the most common are the ABAB design and the multiple-baseline design. An ABAB design, or reversal design, allows a researcher to confirm a treatment effect by showing that behavior changes systematically with conditions of No Treatment (baseline) and Treatment.
Research Design. A. common feature of qualitative projects is that they aim to create. understanding from data as the analysis proceeds. This means. that the research design of a qualitative study differs from that of. a study that starts with an understanding to be tested, where often the. hypothesis literally dictates the form, quantity, and scope of required. data. This sort of design preempts other ways of looking at the research. question.
