If you’ve looked closely enough at my site, you may have noticed the new section to the side - tools and tweaks.
To date, I have built a calculator for graphing and measuring statistical confidence on your tests (alongside the feedback tool and GA content targeting script). It’s the first of its kind to graph split test results freely on a website (at least that I know of).
Check out the split test calculator here - share it and bookmark it if you find it useful.
About the calculator
It’s built with Jquery and the Google Image Charts API to calculate statistically significant changes in conversion rates and even bounce rates. It’s approach is fairly similar to Google Website Optimizer’s so it should yield similar results.
Use it to calculate:
- Landing page testing
- Email marketing split tests
- PPC ad testing
- Calculating changes in bounce rates in your experiments
- Split testing scripts in a call centre
- … and practically any other binomial data
After days of “hard yakka coding”, I really hope you find it useful. As always, tell me what you think of it through the feedback form in the corner. Enjoy!
