Final answer:
Research and experimental expenditures do include costs for testing materials for quality control, which makes the statement true. Experimental controls in scientific research are essential for ensuring valid comparisons between different groups within an experiment. Furthermore, R&D spending should be evaluated in the context of economics and politics to ensure appropriate use of resources.
Step-by-step explanation:
Research and experimental expenditures include a variety of costs associated with the development and testing of new products or services. Among these costs, expenditures for testing of materials for quality control can indeed be part of research and experimental costs. Therefore, the statement is True.
It is important to note that while experiments are a crucial method in scientific research, they come with certain challenges. Experiments can be complex and must be carefully designed to yield valid results. One aspect of a well-designed experiment is the use of experimental controls, such as a control group. Experimental controls are critical because they allow for comparisons between different groups, isolating the effect of the independent variable.
Research and development (R&D), which encompasses various scientific and technical activities, often includes experimenting. However, it's also important to understand the broader context of R&D spending, especially in terms of economics and politics. Federal spending on R&D must be scrutinized to ensure that the funds are being utilized effectively for the intended scientific and economic advancements, rather than being influenced by political motives.
