What is the best way to ensure that the results of your experiment are accurate?

Basically, what you need to do to ensure that the results of your experiments are accurate would be to eliminate all possible biases. Biases are factors that lead to the desired outcome which would then result to the accuracy of the experiment to be lower. This means that no matter how the experiment is well-equipped with equipments and information, if bias is at work, then it would never yield the result it has to yield. Aside from this, gathering all the necessary information would be better as to determine the necessary steps in performing the experiment accurately.
