Final answer:
The theoretical context is not a direct decision in the research design of a quantitative study; instead, decisions revolve around interventions, types of comparisons, and data collection frequency.
Step-by-step explanation:
The research design for a quantitative study involves a number of important decisions, but whether there will be a theoretical context is not typically among them. The essential components of research design that are taken into consideration include whether there will be an intervention, what types of comparisons will be made, and how many times data will be collected. A theoretical context is generally part of the overall research framework, rather than a direct decision in the design of the study's methodology.
