Stumped by the difference between a mean and a median? Unsure when to use percent versus percentage point?
Maybe you went into journalism to avoid math, but fear not. Most analysis in business journalism involves just basic arithmetic. Review the formulas in this tutorial, and in 20 minutes, you’ll be up to speed on how to calculate percent of a whole, percentage change, average, median and mode, plus how to round.
What You Will Learn
- Calculate percent of a whole and percentage change.
- Calculate average (or mean), median and mode.
- Round numbers.
- Use percent versus percentage point.
The tutorial will explain each concept and then offer you a chance to apply what you’ve learned to a real-world exercise. It concludes with an 11-question quiz, again using examples that business journalists are likely to encounter, plus a resource list of books and websites for more information.
The tutorial will take about 20 minutes to complete.
