Answer:
This may be because the two scientists experimented with different methodologies.
Step-by-step explanation:
As we know, through the scientific method, a scientific conclusion only occurs after a few steps, the first being observation, which is the stage in which the scientist observes a particular matter or phenomenon. Two different scientists may make the same observation about a phenomenon, but that does not mean that their experiments would be the same and bring the same conclusions.
After observation, scientists may adopt entirely different methodologies to pursue their scientific experiments. The methodology directly interferes with the conclusion, so two different scientists can make similar observations about a scientific investigation of phenomena and yet present different inferences.
