This post may only be exciting for those who enjoy spending their free time coding in a statistical program (e.g., R, Stata), but I wanted to share an output courtesy of Blake Cutler. Taking per country browser market share data from Net Applications since the beginning of 2008, Blake simply gave a “sum” command (i.e., summarize) for both January 2008 and February 2009:
You’ll notice a few interesting trends:
- The number of countries in the sample has increased over time.
- The mean (or average) Firefox market share, on a per country basis, showed a very healthy increase in the past year. The means of 20.1% and 27.7% are greater than what you see here because they are not weighted in any way (e.g., by region or internet population size).
- Correspondingly, the standard deviation has increased as well.
- The “max” increased from 47.2% to 63.1% (I believe that’s Indonesia).
