Scientific research does not always need to begin with a theory; it can also start with observations or questions arising from empirical data. While theories can guide research by providing a framework for understanding phenomena, exploratory research often leads to the development of new theories. In some cases, a hypothesis derived from existing theories is tested to validate or refine those theories. Ultimately, both theory-driven and exploratory approaches are essential for scientific advancement.

In scientific terms, a theory is a well-substantiated explanation of some aspect of the natural world, based on a body of evidence and extensive testing. It is not just a guess or hypothesis, as commonly understood; rather, it is a robust framework that integrates and explains various observations. In everyday language, "theory" often implies uncertainty or speculation, which can lead to confusion about its scientific significance. Thus, while all scientific theories begin with hypotheses, they evolve into comprehensive explanations supported by rigorous research and validation.
A scientific question is a testable and falsifiable inquiry that seeks to explain a phenomenon or explore a relationship between variables. It is typically specific, measurable, and structured to guide research and experimentation. Such questions often begin with "how" or "why," allowing for systematic investigation and analysis.
A theory is not typically the starting point of an investigation; rather, it often emerges from the analysis of data and observations. Investigations usually begin with research questions or hypotheses based on existing knowledge or observations. Theories are developed to explain patterns and relationships identified during the investigation, providing a framework for understanding the findings and guiding future research.
A theory becomes a fact when that theory is supported by experimental evidence.
hypothesis
No (False)
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.
once a hypothesis has been supported in repeated experiments, scientists can begin to develop a theory.

When writing research questions, you should begin with clear and specific guidelines to ensure the focus and relevance of your study.
Grounded theory research is a systematic approach that allows theories to emerge from the data through a process of constant comparison and theoretical sampling. Unlike other forms of qualitative research, grounded theory does not begin with a preconceived theory or hypothesis. It aims to develop a new theory or framework based on the data collected.

all of the above
Not necessarily... it simply means the earlier theory was based on information available at that time it was proposed. Humans are pretty good at making advances in the scientific world... experiments almost always bring new information to light - allowing us to adapt or update existing information.
