Which phrase describes evidence reasons to support a claim and opinion form based on facts scientific information

The phrase you're looking for is "empirical evidence." Empirical evidence refers to information that is acquired by observation or experimentation. Scientists use empirical evidence to support their claims and hypotheses, as it is based on objective facts that are observable and measurable. When forming an opinion or argument in scientific contexts, it is crucial to base conclusions on empirical evidence rather than on personal beliefs or biases. This ensures that the argument is credible and grounded in reality.

When a claim is supported by empirical evidence, it indicates that the evidence has been gathered through scientifically valid methods, such as controlled experiments, observational studies, and statistical analyses. This type of evidence is often peer-reviewed and published in scientific journals, further validating its reliability.
