Question

The collective body of observations of a natural phenomenon on which scientific explanations are based is called?

Answer 1

Experimental Evidence.

Scientists conduct experiments or observations to gather evidence that either support or disprove a given hypothesis. Hence, all the scientific explanations are based on this body of observations.

Answer 2

The collective body of observations of a natural phenomenon on which scientific explanations are based is called emphirical evidence.

Explanation:

The information and data received through observations and experience by performing various kinds of experiments to conclude and predict the pattern of a phenomeno with the help of science to explain its behaviour is called empirical or experimental evidence.

This is helpful for the researchers and developers as it gives further insights about the phenomeno and paves way for them to proceed or to further conduct experiments resulting in some conclusions.
