Step-by-step explanation:
An interpretation of the results of many tests is called a theory. A theory is a well-substantiated explanation of an aspect of the natural world. It is a scientific explanation that has been repeatedly tested and supported by many experiments.
For example, the theory of evolution is a well-supported explanation of how species have evolved over time. It is based on extensive research and experimentation.
It is important to note that a theory in science is different from the everyday use of the word, which often refers to a guess or speculation. In science, a theory is a well-tested and supported explanation.
