Theory can be classified as which of the following?

The classification of theory as descriptive or explanatory is significant in understanding its function and purpose in various fields. A descriptive theory aims to outline and characterize phenomena as they exist, providing a detailed account of the observed elements and their interrelations. It answers questions such as "What is happening?" or "What are the components involved?"

In contrast, an explanatory theory goes further by addressing the reasons behind the phenomena, offering insights into "Why is this happening?" or "What causes these events?" This distinction is crucial in disciplines ranging from the sciences to social studies, as it affects the development of real-world applications and interventions.

While other classifications like qualitative or quantitative and theoretical or practical provide useful insights into how theories are constructed and used, the descriptive and explanatory framework is particularly valuable in clarifying the roles that different theories play in knowledge creation and in shaping our understanding of complex issues. This makes the classification as descriptive or explanatory the most relevant and effective in terms of understanding the scope and utility of various theories.
