How do scientists ensure that their conclusions are reliable?

Question

A) By ignoring unexpected results
B) By using large sample sizes and repeating experiments
C) By changing data to fit the hypothesis
D) By avoiding the use of a control group

Answer 1

B) By using large sample sizes and repeating experiments

Scientists ensure that their conclusions are reliable by conducting multiple experiments with large sample sizes, which helps to reduce the impact of random errors and increase the validity of the results. This process also often involves peer review, where other experts evaluate the research methods and findings. Ignoring unexpected results, changing data to fit a hypothesis, and avoiding control groups would undermine the integrity of the scientific process.
