Which of the following is a characteristic of reliable scientific study

A reliable scientific study is supported by empirical evidence.

Explanation:

Science is the set of knowledge that is organized systematically obtained from observation, experimentation and reasoning within specific areas. In other words, science is empirical knowledge of the universe that is established according to the principles of the scientific method. The scientific method will vary according to the type of field of study, but you can define how the process by which a theory can be demonstrated or refuted. The scientific method is then defined as a set of ordered steps that are used to acquire new knowledge. In order to be qualified as a scientist, it must be based on empiricism, on measurement and, in addition, must be subject to reason. It is characterized by reproducibility, that is, the ability to repeat a given experiment, anywhere and by anyone. Another characteristic of the scientific method is refutability, that is, that every scientific proposition has to be susceptible to being falsified or refuted. This implies that experiments could be designed, which, in the case of giving different results to those predicted, would deny the hypothesis tested.

Then, as a reliable scientific study and science is based on the scientific method, which in turn is supported by experimental evidence, it is possible to say that a reliable scientific study is supported by empirical evidence.
