Final answer:
The statement that shows bias in scientific research is the one suggesting that c) "A study selectively presents data to support a predetermined conclusion." violating the objective approach required in scientific methodology.
Step-by-step explanation:
The statement that illustrates bias in scientific research is c) "A study selectively presents data to support a predetermined conclusion." This reflects a scenario where the scientific method is compromised by allowing subjective influence to shape the outcome, which is contrary to the objective nature of scientific inquiry.
In scientific research, it is imperative to collect data objectively and to conduct controlled experiments to test hypotheses without bias. Only by eliminating the selective presentation of data can researchers ensure that their conclusions are based on the full range of evidence. This is fundamental for the integrity of scientific findings, which must be based on empirical observation and reproducible proof.
