I'm pretty sure you haven't read the statements right before the table:
W3Schools.com is for people with an interest for web technologies. This fact indicates that the figures below might not be 100% true for the average internet users. (...) Anyway, our data, collected from W3Schools' log-files over ten years, clearly shows the long term trends.
But if you're not convinced, you can read in their forums:
- The w3schools Browser and OS statistics are based on the data
collected over the w3schools site or do have more sources?
- Only the W3Schools site.
