empirical equations

Empirical equations are mathematical formulas derived from observed data rather than theoretical models. They help describe relationships between variables based on real-world measurements, making predictions or understanding trends. For instance, scientists might use an empirical equation to relate temperature and pressure in gases, based on experimental results. These equations are valuable in various fields, including physics, chemistry, and economics, as they provide practical insights that are often easier to apply than complex theoretical formulas. However, they are specific to the conditions under which they were derived and may not universally apply outside those conditions.
