Variation differences between what we are analyzing: statistics helps make sense of variation, though decreasing the number of variations in a given problem, makes the data easier to understand. For softwares that convert handwriting to online text, imagine the variation in data that needed to be collected in order for the software to recognize a given handwriting. Data the observations recorded: data is numbers in context , data needs context in order to be useful. The interpretation of data is just as important as the calculation. Numeric numeric data describes the quantity of the object(s) in question: numeric data will always be a number.
