The scientific method or scientific analysis can be defined as the objective search for the truth. When a scientist does an experiment, it is essential that he reports every observation in the result, whether it is in uniformity with the experiment or not. Many scientific discoveries are made based on the unusual findings. The failure to report these unusual findings during an experiment might result in the loss of vital information.
