Trick of the month:
Comparing relative changes
with logarithmic scales
July 2010
Greetings, fellow data analysts!
As the old saying goes, all good things come back someday. We, for sure, certainly hope so! Back in the Sixties, for example, people almost always used logarithmic scales to draw statistical charts for revenues, prices or costs. After all, how else could someone see a percentage change - which is what matters in the first place? Back then, processing data was very time-consuming, and creating charts required lots of patience and special materials like logarithmic paper. In fact, software
has made this process so much easier that no one even makes logarithmic paper anymore. But that is no reason to forget these tried-and-true practices. In our seminars and presentations, we often make a case for logarithmic scales because they are the only way to make percentage changes comparable. We often feel, though, that our words are met with skepticism or even discomfort. In this edition of clicks!, we want to show you why logarithmic scales are so important and how DeltaMaster makes it easy to work with them.
Here's to the comeback of logarithmic scales - because they are good for the quality of our reports as well as our information culture in general.
Best regards,
