What distinguishes empirical data from theoretical data?

1. Empirical data is speculative, while theoretical data is factual

2. Empirical data is based on measurement, while theoretical data is based on assumptions

3. Empirical data can only be qualitative

4. There is no distinction; both terms are synonymous

The correct answer is: Empirical data is based on measurement, while theoretical data is based on assumptions

Empirical data is distinguished by its basis in direct observation or measurement. It is collected through experiments or real-world observations and reflects factual information that can be verified. This type of data provides concrete evidence and supports conclusions drawn from actual experiences and tests in the field. On the other hand, theoretical data is rooted in hypotheses, models, or assumptions that explain phenomena but may not be directly measurable or observed. Theoretical data often serves to predict outcomes or understand underlying principles, but without the empirical evidence to support these theories, they remain speculative in nature. Understanding this distinction is crucial for fire investigators, as it enables them to distinguish between what has been observed in fires and what has been theorized about fire behavior based on models or existing knowledge. Ultimately, the reliance on empirical data enhances the accuracy and reliability of investigations.
