Developments in the field of statistical data analysis often parallel or follow advancements in other fields to which statistical methods are fruitfully applied. Data is known to be crude information and not knowledge by itself. The sequence from data to knowledge is: from Data to Information, from Information to Facts, and finally, from Facts to Verification of Truth. Data becomes information, when it becomes relevant to your research problem. Information becomes fact, when the data can support it. Facts are what the data reveals. However, the decisive instrumental (i.e., applied) knowledge is expressed together with some statistical degree of confidence. Lastly, I do hope that this in-depth knowledge will create an awareness to promote the use of statistical thinking and techniques to apply them to make educated decisions whenever there is variation in data.
