Many journalists do not grasp just how important numbers are in reporting. In the world around us, numbers are everywhere, from statistics of baseball games to percentiles in school testing. These numbers are not only everywhere, but relevant to the reporter’s job of informing the public. Understanding the language of numbers means understanding the style of writing with numbers, including when to use numerals or to spell words out and when to use one word instead of another.
Percentages become very useful in articulating to the reader more clearly. Rather than using fractions, which can be confusing, journalists can use a more clear, concise number for calculations ranging from compounding interest to payments on loans.
Journalists encounter statistics regularly and when they understand the language, communication between the writer and the reader can become more enjoyable. Statistics are helpful in determining probability, lottery odds and standard deviations. Not only are there the everyday statistics, but there are also federal statistics such as unemployment rates.
