Research is commonly divided into various categories. Which category is NOT typically recognized?

In the context of research categorization, applied research, development research, and pure research are widely recognized types, each serving distinct purposes.

Applied research is designed to solve specific practical problems and is often goal-oriented, focusing on immediate application in real-world situations. It's frequently utilized in fields such as healthcare, education, and engineering to develop solutions based on theoretical frameworks.

Pure research, also known as basic or fundamental research, is aimed at gaining knowledge for its own sake, without a direct application in mind. It seeks to expand understanding of underlying principles and theories and is essential for the long-term advancement of knowledge across various fields.

Development research typically involves the systematic use of knowledge gained from both applied and pure research to develop new products or processes. This is crucial in sectors such as technology and pharmaceuticals where innovation is propelled by advancements in understanding.

Conversely, functional research is not a standard category in common research frameworks, which is why it stands out as the option that is not typically recognized. It does not fall into established classifications of research like the aforementioned types, making it less relevant or widely accepted in academia and professional practice.
