Question

What happens when the data in an investigation do not support the original hypothesis

Answer 1

When the data in an investigation does not support the original hypothesis, you can modify your hypothesis to support the experimental data. However, you should NEVER change your experimental data to fit your hypothesis.

Answer 2

The hypothesis is an educated, which is based on the researches done in the past and are well established. The hypothesis is a guess, which is testable. The experiments based on the hypothesis are performed and the data is collected. In case, the data obtained from the experiment does not match the hypothesis then the hypothesis may not be valid, hence, the hypothesis needs a revision in such cases.
