Some examples of questions that appear as hypotheses but require testing include whether cooking oil can power a modified diesel engine or whether a new medication is effectiveness for treating a particular condition or disease.

However, providing facts that are statistically able to be tested and analyzed is a way to resolve a theory or hypothesis.

Even though science is ostensibly an objective discipline, researchers hold opinions and stick to their ideas even in the face of contradictory evidence. Research and testing allow scientists to test their own ideas, as well as those of others, to pursue answers that either confirm or rule out the ideas under analysis. Even when proven, no scientific idea becomes an ironclad fact, but it can become a theory that leads to further research. As theories build on one another, the scientific community makes progress in its various disciplines.
