Answer:
A testable hypothesis is valuable, even if evidence shows that it is false
Explanation:
A hypothesis sets a base on which the experiment is conducted by determining the design and protocol for which the scientists will take in the experiment. A hypothesis, therefore, should be developed based on good research prior to beginning to conduct the experiment. Usually a good hypothesis is one of no change called a 'null hypothesis'. Based on an analysis of data from the experiment, a hypothesis could either be rejected or accepted. If the null hypothesis is rejected then the alternative - which is usually the flip side of the null hypothesis- is adopted as true.
